Types of real time remote temperature monitoring systems

Real Time Temperature Monitoring for Medical Refrigerator
While selecting a system for your requirements, consider the following questions before your decision making:
What are the parameters (eg. Temperature, humidity, pressure etc.) you want to monitor for each asset? If you have different assets such as refrigerators, cold rooms, warehouses etc. you may have to list out the parameter to be monitored for each asset.
What is the type of communication you prefer viz., WiFi, Rf etc.? If you want flexibility to frequently relocate your assets such as lot of refrigerators, small freezers etc., you may choose WiFi, Rf or Zigbee mode of communication. Also if you have moving racks in a warehouse it is ideal to use WiFi, Rf or Zigbee.
If you have only fixed assets you can go for Ethernet or IP based systems which may work out to be economical.
What are the type of alerts you want viz. Email, SMS, voice call, local hooter etc.
The sensor should continue to function even in case of power failure or communication failure. Hence, the sensors should have its own memory store the data and should be able to transmit the data to the base station once power or communication is restored.
If generating alert is your priority, the alert system should continue to function even in the case of power failure, server failure or communication failure. This means that the alert system should be independent and should have a battery backup.
What is the accuracy required by you for each parameter? Eg. if you want an accuracy of 0.1 °C, you may have to select accordingly. A sensors with 0.5 °C accuracy will be cheaper than that of 0.1 °C.
Do you want to see the current readings in each sensor screen? There are sensors with and without displays. eg. In a warehouse where you are placing sensors in inaccessible areas, you may not want a sensor with a display. In such cases, you can go for sensors without display which will be cheaper. The readings will be seen in the base station or a computer connected to the base stations
What is the memory capacity of each sensor? A sensors with memory capacity of 8000 readings means that it will store 8000 readings at a time. This means that if readings is taken every minute, the memory will last for 8000 minutes which is almost 5.5 days. eg. If you are afraid of frequent power failure or server failure, you may prefer to go for sufficient memory capacity.
If you are following US standards, you may prefer to have 21 CFR Part 11 compliant devices. This means that the manufacturer of the device should have tested the devices, software etc. for compliance with 21 CFR Part 11.
Is there an annual fee for the system or is it a one-time package?
Is it easy to calibrate the sensors each year?
Do you have provision to give electric power for each sensor? In such case, you have to provide electric power plugs for each sensor. Most of the Ethernet and Wifi type of sensors require power. However there are POE (Power over Ethernet) type sensors also available, but may be without battery backup. These type sensors generally have a longer battery life and may not need individual power plugs
If the sensors are not connected to power, you may need to check whether the battery of the sensor and the base station are rechargeable type.
Also please check how long the battery lasts after each recharge.
For sensors without a power supply, the sensor should generate an alert when the battery charge goes down to critical levels.
It will be very easy if the software can be operated from a web browser instead of installing a software. In such case, you can check the current data from any computer using your user id and password. Also, if it is browser based you can check on your mobile phone as well.
If you are more technically inclined you may prefer to use a mobile based application and you may like to check whether the supplier has a mobile application.
You may use this evaluation sheet for evaluating different manufacturers while selecting a remote monitoring system.

 

Hospital Rooms Monitoring

In hospitals, critical parameters of patient rooms need to be continuously monitored, recorded and alerts generated if required. This will be required in many cases as regulatory requirement. Such monitoring systems are required for patient rooms, Operation Theater, isolation ward etc.
What are the parameters to be monitored in patient rooms?

Hospital Room Temperature Humidity Monitor
Generally the following parameters need to be monitored and recorded:
Temperature of the room has to be continuously monitored. The temperature level should not exceed the specified levels.
Humidity of the room also need to be monitored, because high or low humidity will cause discomfort to the patients.
Pressure monitoring is required especially in critical rooms and isolation wards. This will be basically differential pressure monitoring, which is comparison of pressure inside and outside the room.
How to select a hospital room monitoring system?

While selecting a suitable system, you may consider the following factors:
For an existing room, you may prefer to use a device which does not require power supply. In such case you can avoid new power connections.
If all the rooms are having WiFi, a WiFi based system is preferred, again because there will be no wiring required.
Hospital Room Temperature data xls
The unit should have a display so that the occupants or the attending staff can see the readings on the screen.
It should be capable of generating at least Email & SMS alerts and phone call alerts for very critical rooms
If it is a self-contained battery unit, the battery power should last a couple of months at least so that frequent recharging is not required.
Email or SMS alerts should be generated in case of low battery or WiFi disruption
It should be possible to generate periodic reports so that you can download the reports for your records
If it is a cloud based system, you can check the data even if you are outside the hospital premises. So in case of an alert you can check the current status and take corrective action accordingly.
Differential pressure monitoring is generally of critical nature and should be able to generate a local alarm and preferably phone call alert
Differential pressure monitoring system also can be connected to a local network and data can be recorded. You have to decide based on your requirements

BMS based monitoring system for hospitals

Building Management System (BMS) is used in buildings for various critical parameters around the entire building. The parameters can be temperature, humidity, pressure, water level, smoke detection, door openings etc. In fact, any parameter to be monitored can be incorporated using different sensors. There will be central processors in each floor and possible in each section of the floor. All such controllers collect continuous data from all the sensors and transfer to a centralized computer system. Recording, alert system etc. can be generated through this centralized system. Also, the system can be connected to cloud server for remote monitoring.

Cold Room Monitoring
Cold storage monitoring and walk in freezer monitoring are required for various temperature sensitive items such as medicines, vaccines, fruits, vegetables, fresh food, frozen food etc. which are stored under temperature controlled rooms. The storage time can be from couple of days to couple of years depending on the usage. Hence these items should never exceed permitted temperature and the conditions need to be continuously monitored and recorded. As per regulatory requirements, it might be required to check the recorded data periodically to ensure that the items have been maintained under stipulated conditions. Also nowadays insurance companies insist to have continuous recording so that they can verify upon any claims for damaged goods.
Cold storage monitoring for temperature & humidity

Cold Storage Monitoring System
Cold storages are also known as cold rooms in general and are maintained above 0°C. Generally cold storage monitoring is required for the following parameters:
Temperature inside the cold room to be monitored and recorded. For medicine cold rooms, the temperature will be between 2°C and 8°C
Humidity inside the cold room will be generally high because of condensation. For medicine cold rooms, the humidity has to be generally below 65%. Also for many fruits and vegetables, there are stipulated humidity levels to be maintained. For reducing the humidity, you may have to use dehumidifiers and for increasing humidity you have to use humidifiers
Power failure monitoring is preferred so that operators receive alerts in case of power failure
Walk in Freezer temperature monitoring for humidity

For walk in freezers, the maintained temperature will be below 0°C and can be generally up to –40°C for food items. Walk in freezer monitoring consists of the following systems:
Walk-in-freezer-monitoring-and-alert-
Temperature inside the freezer need to be recorded and monitored.
Humidity is not essential for most of the frozen foods packed in moisture proof packing. However for certain medicines, humidity need to be controlled.
Power failure monitoring is preferred for walk-in freezer also since a loss of power need to be alerted immediately.
How to select a suitable cold room monitoring system?

For selection of a suitable monitoring system, you have to consider the following factors:
It should have a phone call, SMS and email alerts system which should generate alerts if the monitored parameters exceed permitted values.
You should be able to download recorded data for any period from the cold room monitoring system.
For Walk In freezer monitoring system, the sensors should be able to sustain the temperature levels, especially if humidity sensors is required. This is applicable for cold room monitoring system also, but not so severe.
There should be a display of the current readings in a screen in front of the cold room or freezer room.
It should be preferably a cloud based monitoring system so that the data can be viewed and reports generated remotely.

Is there a periodic charge for the software of the refrigerator monitoring system?
Is there a display screen on the device so that you can see next to the refrigerator?
Will it generate email, SMS and Phone call alerts in case temperature or humidity goes high?
Can it also generate email, SMS and Phone call alerts if the door is opened for a long duration?
Wireless Refrigerator monitoring system
If you want to move the refrigerator to another room or for maintenance, can you easily
disconnect the system and reconfigure? (If you use Radio frequency systems, moving to another room will always be a problem since you need transmitters & receivers to be configured)
Can you monitor refrigerators & freezers from multiple locations in a single software?
Our solution for refrigerator temperature monitoring:

We provide a complete solution for refrigerator monitoring in hospitals, laboratories etc. As explained in the next section, a WiFi monitoring system will be ideal when you have large number of refrigerators and freezers.

Cloud based monitoring system is available without any extra cost. The data is uploaded every minute and hence static IP address is not required.
Email, SMS and Phone call alerts can be generated to 4 operators. If temperature or humidity goes beyond the programmed limits, the alerts will be generated.
Why we recommend WiFi monitoring system for refrigerators especially in hospitals?

Even though we are supplying monitoring solutions based on Ethernet, WiFi, Radio frequency and Zigbee technology, we prefer WiFi monitoring solutions for medical refrigerators for the following reasons:
Refrigerator Temperature Monitoring
A new WiFi network can be easily setup with a budget of under $50.00
So if you want to make a new room with multiple refrigerators, you can connect all these devices in a single WiFi monitoring system
Depending upon the strength of the network, you can connect 20 to 30 devices in a single WiFi network.
If you want to change the refrigerators or add refrigerators, it is easy to configure in a WiFi monitoring system compared to a Ethernet system.
In case of Rf (radio frequency) or Zigbee network, if you want to add a new refrigerator in a new room, you may need to add additional receiver even for a single device which will become costly.
For configuration of Rf or Zigbee sensor, you always have to depend on the original
supplier, Chart of Rerigerator Monitoring Software whereas WiFi device can be configured by any IT technician.
Inserting the Temperature sensor in Glycol bottle

For a refrigerator, the door opening is very frequent and hence there will be regular temperature fluctuations. Such regular fluctuation will cause false alarms as well. In order to prevent same, the sensors inside refrigerator are inserted inside a glycol bottle. The temperature properties of glycol are similar to that of medicines and hence the temperature inside the glycol bottle will be recorded and alerts will be generated accordingly.

 

Warehouse Monitoring
A warehouse used for storage of medicine, chemicals, food items, electronics etc. are under controlled conditions of temperature & humidity. In many of these cases, it is required to record and monitor the temperature and humidity to meet regulatory requirements and internal quality assurance procedures.
What are the requirements for a warehouse monitoring system?
Inside a warehouse, generally the following parameters need to be monitored:
warehouse temperature monitoring sensor
The temperature of the warehouse has to be recorded and monitored. Depending on the size and shape of the area, you may need to use multiple sensors inside the warehouse. If you are using the area for storage of medicines, the locations of the sensors of the warehouse monitoring system are decided after conducting a temperature mapping study.
The humidity of the area also needs to be recorded and monitored based on the type of goods being stored and the humidity conditions of the location. Generally for items such as medicine, chemicals, tobacco etc., humidity also is important and hence need to be recorded and monitored.
Power failure needs to be critically monitored. In the case of power failure especially after working hours, the operators need to be alerted so that proper action can be taken on time.
How to select a suitable warehouse temperature monitoring system?

While selecting a temperature and humidity warehouse monitoring system, you have to consider the following aspects.
Refrigerator remote monitoring screen global
It is preferred to use a wireless system (Radio frequency or Zigbee) which does not require a power supply. You may have to install the sensors at inaccessible places and pulling a power line and an Ethernet cable will be practically difficult.
Also, a wireless remote monitoring system is preferred because you will have pallets and boxes being loaded using a forklift and should never touch a wire which will cause damages.
You may need to rearrange the sensors depending on the hot and cold points inside the area. In case the sensors are wired, it will be extremely difficult to change the locations at a later date.
The battery life of the sensors should be 8 to 12 months so that it does not require frequent recharging. The batteries should be preferably rechargeable type.
The warehouse remote monitoring system should generate Email or SMS alerts if the battery is low or if there is a problem with data transfer.
The system should generate email, SMS and voice call alerts as per your preference. Also, it should be able to generate alerts to 3 to 4 operators with different type of alerts. Eg . operator 1 should get a phone call, operator 2 should get only SMS etc.
It should be possible to see the readings of different sensors of the entire warehouse in a TV screen at a central location so that anyone can check the temperature. It is preferred if it can be the layout drawing of the warehouse superimposed with readings at a different location. SO in a single look you can see the entire warehouse plan and see all temperature readings at different locations. If any of the readings are high, it should indicate in a red colour.
Refrigerator Sensor Side View
It should be cloud based server so that live data can be seen even if you are outside the warehouse over a laptop, smart phone etc. Also, if an alert comes, you can check the situation even if you are outside the warehouse and take decisions accordingly.
If you want to get the data of your truck when it reaches your warehouse, please select a system accordingly. In such case one sensor will be fitted in the truck. When the truck goes out of the warehouse it will record the data and when the truck reaches back to the warehouse it will transfer the entire data to the centralized system. So as soon as the truck is received manual data transfer is not required.
You should be able to generate weekly, monthly reports or for any custom date range.
You should be able to add more sensors easily without much of assistance.
Our solutions for warehouse remote monitoring

Temperature monitoring system which is ideally suited for warehouses and large factories. Protocol is similar to a radio frequency (Rf) system but operate in a different frequency. This basically consists of one receiver and many transmitter sensors. The sensors continuously transmit data to the receiver. The receiver will be connected to a computer or LAN network through which cloud-based monitoring and alert are generated. One receiver can receive signals from 50 to 60 sensors. The distance between a sensor and receiver can be up to 800 meters to 1 km (line of sight). However depending on the size and layout of the area, you may have to use more than one receiver.
Features:

Fridge Monitoring Report
Major features of the same briefed below:
Each sensor has its own display on which you can see current readings. Also, critical functional parameters can be seen on this screen
Communication distance of approximately 1 km line of sight. This means that if there is no obstruction between the receiver and the transmitter, they can communicate each other for upto 1 km.
Phone call, email and SMS alerts can be generated in case temperature or humidity goes above or below the programmed limits. The delay period also can be programmed. If the temperature goes below 8°C for 3 minutes or below 0°C for 30 seconds, the alarm can be generated
Alert is generated if there is communication error and also for low battery.
Battery lasts from 8 to 10 months without recharging.

Operating principle of real time monitoring system

wireless real time monitoring systems global
The basic principle of all such systems involve lot of sensors such as temperature sensor, humidity sensor, pressure sensor etc. These sensors continuously collect data at preprogrammed intervals known as sampling interval. The sampling interval can vary from micro seconds to hours based on the criticality of the parameter being monitored. All the sensors continuously communicate the collected data to a central base station. The mode of communication from the sensors to the base station can be in different modes as explained in the next article. This base station transmits the collected data to the internet. Also, this base station continuously analyzes the data for any alerts. If any of the parameters exceed the preprogrammed alert levels, alerts such as email, SMS, voice call etc. will be generated to the operators.

Types of real time remote temperature monitoring systems

Based on the technology of the device there are different types of monitoring systems as explained below:
Ethernet-based real-time monitoring systems
The sensors are connected to an Ethernet system through CAT6 cables and connectors, just similar to connecting a computer, printer etc. You will need to have Ethernet ports near to each sensor. These can be powered from an electrical plug or can be POE type (Power over Ethernet). There will not be a separate base station, but a computer in the network can act as the base station.
WiFi communication based real time remote temperature monitoring system
Here there is no Ethernet cabling required. The communication between the sensor and the central station takes place through WiFi routers used for connecting all other computers. The WiFi communication needs power and if you need continuous data transmission, you may have to go for sensors which are powered through an AC supply. There are devices available which continuously collect data and stores in itself and transmits the data only once or twice in a day. Such systems can work on its own battery for a long duration since it is connecting to WiFi only once or twice in a day.
alarm screen remote monitoring system
In this case also there will not be a separate base station, but a computer in the network can act as the base station. The communication reliability depends on the strength and range of the WiFi router.
Radio Frequency based real-time remote temperature monitoring system
These work on Radio frequency. While selecting a device you have to check that the device works on the radio frequency approved by the local authorities. The supplier has to take approval for the device from the authorities. These devices have a comparatively long range of communication from the base station. The base station acts as a receiver and the sensors act as transmitters. There will be continuous interaction between the sensors and the base station.
Such sensor operates with a very low power requirement and hence can have a long battery life without supporting power supply.

Also if you have moving racks in a warehouse it is ideal to use WiFi, Rf or Zigbee.
If you have only fixed assets you can go for Ethernet or IP based systems which may work out to be economical.
What are the type of alerts you want viz. Email, SMS, voice call, local hooter etc.
The sensor should continue to function even in case of power failure or communication failure. Hence, the sensors should have its own memory store the data and should be able to transmit the data to the base station once power or communication is restored.
If generating alert is your priority, the alert system should continue to function even in the case of power failure, server failure or communication failure. This means that the alert system should be independent and should have a battery backup.
What is the accuracy required by you for each parameter? Eg. if you want an accuracy of 0.1 °C, you may have to select accordingly. A sensors with 0.5 °C accuracy will be cheaper than that of 0.1 °C.
Do you want to see the current readings in each sensor screen? There are sensors with and without displays. eg. In a warehouse where you are placing sensors in inaccessible areas, you may not want a sensor with a display. In such cases, you can go for sensors without display which will be cheaper. The readings will be seen in the base station or a computer connected to the base stations
What is the memory capacity of each sensor? A sensors with memory capacity of 8000 readings means that it will store 8000 readings at a time. This means that if readings is taken every minute, the memory will last for 8000 minutes which is almost 5.5 days. eg. If you are afraid of frequent power failure or server failure, you may prefer to go for sufficient memory capacity.
If you are following US standards, you may prefer to have 21 CFR Part 11 compliant devices. This means that the manufacturer of the device should have tested the devices, software etc. for compliance with 21 CFR Part 11.
Is there an annual fee for the system or is it a one-time package?
Is it easy to calibrate the sensors each year?
Do you have provision to give electric power for each sensor? In such case, you have to provide electric power plugs for each sensor. Most of the Ethernet and Wifi type of sensors require power. However there are POE (Power over Ethernet) type sensors also available, but may be without battery backup. These type sensors generally have a longer battery life and may not need individual power plugs
If the sensors are not connected to power, you may need to check whether the battery of the sensor and the base station are rechargeable type.
Also please check how long the battery lasts after each recharge.
For sensors without a power supply, the sensor should generate an alert when the battery charge goes down to critical levels.
It will be very easy if the software can be operated from a web browser instead of installing a software. In such case, you can check the current data from any computer using your user id and password. Also, if it is browser based you can check on your mobile phone as well.
If you are more technically inclined you may prefer to use a mobile based application and you may like to check whether the supplier has a mobile application.
You may use this evaluation sheet for evaluating different manufacturers while selecting a remote monitoring system.

 

Hospital Rooms Monitoring

In hospitals, critical parameters of patient rooms need to be continuously monitored, recorded and alerts generated if required. This will be required in many cases as regulatory requirement. Such monitoring systems are required for patient rooms, Operation Theater, isolation ward etc.
What are the parameters to be monitored in patient rooms?

Hospital Room Temperature Humidity Monitor
Generally the following parameters need to be monitored and recorded:
Temperature of the room has to be continuously monitored. The temperature level should not exceed the specified levels.
Humidity of the room also need to be monitored, because high or low humidity will cause discomfort to the patients.
Pressure monitoring is required especially in critical rooms and isolation wards. This will be basically differential pressure monitoring, which is comparison of pressure inside and outside the room.
How to select a hospital room monitoring system?

While selecting a suitable system, you may consider the following factors:
For an existing room, you may prefer to use a device which does not require power supply. In such case you can avoid new power connections.
If all the rooms are having WiFi, a WiFi based system is preferred, again because there will be no wiring required.
Hospital Room Temperature data xls
The unit should have a display so that the occupants or the attending staff can see the readings on the screen.
It should be capable of generating at least Email & SMS alerts and phone call alerts for very critical rooms
If it is a self-contained battery unit, the battery power should last a couple of months at least so that frequent recharging is not required.
Email or SMS alerts should be generated in case of low battery or WiFi disruption
It should be possible to generate periodic reports so that you can download the reports for your records
If it is a cloud based system, you can check the data even if you are outside the hospital premises. So in case of an alert you can check the current status and take corrective action accordingly.
Differential pressure monitoring is generally of critical nature and should be able to generate a local alarm and preferably phone call alert
Differential pressure monitoring system also can be connected to a local network and data can be recorded. You have to decide based on your requirements

Cold Room Monitoring
Cold storage monitoring and walk in freezer monitoring are required for various temperature sensitive items such as medicines, vaccines, fruits, vegetables, fresh food, frozen food etc. which are stored under temperature controlled rooms. The storage time can be from couple of days to couple of years depending on the usage. Hence these items should never exceed permitted temperature and the conditions need to be continuously monitored and recorded. As per regulatory requirements, it might be required to check the recorded data periodically to ensure that the items have been maintained under stipulated conditions. Also nowadays insurance companies insist to have continuous recording so that they can verify upon any claims for damaged goods.
Cold storage monitoring for temperature & humidity

Cold Storage Monitoring System
Cold storages are also known as cold rooms in general and are maintained above 0°C. Generally cold storage monitoring is required for the following parameters:
Temperature inside the cold room to be monitored and recorded. For medicine cold rooms, the temperature will be between 2°C and 8°C
Humidity inside the cold room will be generally high because of condensation. For medicine cold rooms, the humidity has to be generally below 65%. Also for many fruits and vegetables, there are stipulated humidity levels to be maintained. For reducing the humidity, you may have to use dehumidifiers and for increasing humidity you have to use humidifiers
Power failure monitoring is preferred so that operators receive alerts in case of power failure
Walk in Freezer temperature monitoring for humidity

For walk in freezers, the maintained temperature will be below 0°C and can be generally up to –40°C for food items. Walk in freezer monitoring consists of the following systems:
Walk-in-freezer-monitoring-and-alert-
Temperature inside the freezer need to be recorded and monitored.
Humidity is not essential for most of the frozen foods packed in moisture proof packing. However for certain medicines, humidity need to be controlled.
Power failure monitoring is preferred for walk-in freezer also since a loss of power need to be alerted immediately.
How to select a suitable cold room monitoring system?

For selection of a suitable monitoring system, you have to consider the following factors:
It should have a phone call, SMS and email alerts system which should generate alerts if the monitored parameters exceed permitted values.
You should be able to download recorded data for any period from the cold room monitoring system.
For Walk In freezer monitoring system, the sensors should be able to sustain the temperature levels, especially if humidity sensors is required. This is applicable for cold room monitoring system also, but not so severe.
There should be a display of the current readings in a screen in front of the cold room or freezer room.
It should be preferably a cloud based monitoring system so that the data can be viewed and reports generated remotely.

Why we recommend WiFi monitoring system for refrigerators especially in hospitals?

Even though we are supplying monitoring solutions based on Ethernet, WiFi, Radio frequency and Zigbee technology, we prefer WiFi monitoring solutions for medical refrigerators for the following reasons:
Refrigerator Temperature Monitoring
A new WiFi network can be easily setup with a budget of under $50.00
So if you want to make a new room with multiple refrigerators, you can connect all these devices in a single WiFi monitoring system
Depending upon the strength of the network, you can connect 20 to 30 devices in a single WiFi network.
If you want to change the refrigerators or add refrigerators, it is easy to configure in a WiFi monitoring system compared to a Ethernet system.
In case of Rf (radio frequency) or Zigbee network, if you want to add a new refrigerator in a new room, you may need to add additional receiver even for a single device which will become costly.
For configuration of Rf or Zigbee sensor, you always have to depend on the original
supplier, Chart of Rerigerator Monitoring Software whereas WiFi device can be configured by any IT technician.
Inserting the Temperature sensor in Glycol bottle

For a refrigerator, the door opening is very frequent and hence there will be regular temperature fluctuations. Such regular fluctuation will cause false alarms as well. In order to prevent same, the sensors inside refrigerator are inserted inside a glycol bottle. The temperature properties of glycol are similar to that of medicines and hence the temperature inside the glycol bottle will be recorded and alerts will be generated accordingly.

 

Warehouse Monitoring
A warehouse used for storage of medicine, chemicals, food items, electronics etc. are under controlled conditions of temperature & humidity. In many of these cases, it is required to record and monitor the temperature and humidity to meet regulatory requirements and internal quality assurance procedures.
What are the requirements for a warehouse monitoring system?
Inside a warehouse, generally the following parameters need to be monitored:
warehouse temperature monitoring sensor
The temperature of the warehouse has to be recorded and monitored. Depending on the size and shape of the area, you may need to use multiple sensors inside the warehouse. If you are using the area for storage of medicines, the locations of the sensors of the warehouse monitoring system are decided after conducting a temperature mapping study.
The humidity of the area also needs to be recorded and monitored based on the type of goods being stored and the humidity conditions of the location. Generally for items such as medicine, chemicals, tobacco etc., humidity also is important and hence need to be recorded and monitored.
Power failure needs to be critically monitored. In the case of power failure especially after working hours, the operators need to be alerted so that proper action can be taken on time.
How to select a suitable warehouse temperature monitoring system?

While selecting a temperature and humidity warehouse monitoring system, you have to consider the following aspects.
Refrigerator remote monitoring screen global
It is preferred to use a wireless system (Radio frequency or Zigbee) which does not require a power supply. You may have to install the sensors at inaccessible places and pulling a power line and an Ethernet cable will be practically difficult.
Also, a wireless remote monitoring system is preferred because you will have pallets and boxes being loaded using a forklift and should never touch a wire which will cause damages.
You may need to rearrange the sensors depending on the hot and cold points inside the area. In case the sensors are wired, it will be extremely difficult to change the locations at a later date.
The battery life of the sensors should be 8 to 12 months so that it does not require frequent recharging. The batteries should be preferably rechargeable type.
The warehouse remote monitoring system should generate Email or SMS alerts if the battery is low or if there is a problem with data transfer.
The system should generate email, SMS and voice call alerts as per your preference. Also, it should be able to generate alerts to 3 to 4 operators with different type of alerts. Eg . operator 1 should get a phone call, operator 2 should get only SMS etc.
It should be possible to see the readings of different sensors of the entire warehouse in a TV screen at a central location so that anyone can check the temperature. It is preferred if it can be the layout drawing of the warehouse superimposed with readings at a different location. SO in a single look you can see the entire warehouse plan and see all temperature readings at different locations. If any of the readings are high, it should indicate in a red colour.
Refrigerator Sensor Side View
It should be cloud based server so that live data can be seen even if you are outside the warehouse over a laptop, smart phone etc. Also, if an alert comes, you can check the situation even if you are outside the warehouse and take decisions accordingly.
If you want to get the data of your truck when it reaches your warehouse, please select a system accordingly. In such case one sensor will be fitted in the truck. When the truck goes out of the warehouse it will record the data and when the truck reaches back to the warehouse it will transfer the entire data to the centralized system. So as soon as the truck is received manual data transfer is not required.
You should be able to generate weekly, monthly reports or for any custom date range.
You should be able to add more sensors easily without much of assistance.
Our solutions for warehouse remote monitoring

Temperature monitoring system which is ideally suited for warehouses and large factories. Protocol is similar to a radio frequency (Rf) system but operate in a different frequency. This basically consists of one receiver and many transmitter sensors. The sensors continuously transmit data to the receiver. The receiver will be connected to a computer or LAN network through which cloud-based monitoring and alert are generated. One receiver can receive signals from 50 to 60 sensors. The distance between a sensor and receiver can be up to 800 meters to 1 km (line of sight). However depending on the size and layout of the area, you may have to use more than one receiver.
Features:

Phone call, email and SMS alerts can be generated in case temperature or humidity goes above or below the programmed limits. The delay period also can be programmed. If the temperature goes below 8°C for 3 minutes or below 0°C for 30 seconds, the alarm can be generated
Alert is generated if there is communication error and also for low battery.
Battery lasts from 8 to 10 months without recharging.

Remote temperature monitoring

 

For lot of applications, the critical parameters such as temperature, humidity, pressure etc. need to be monitored and recorded in real time preferably with an alert system to generate alerts in case the parameters exceed the permitted levels. These are generally known as real time monitoring systems. Temperature is the most common parameter being monitored and hence is commonly referred as remote temperature monitoring.

Operating principle of real time monitoring system

wireless real time monitoring systems global
The basic principle of all such systems involve lot of sensors such as temperature sensor, humidity sensor, pressure sensor etc. These sensors continuously collect data at preprogrammed intervals known as sampling interval. The sampling interval can vary from micro seconds to hours based on the criticality of the parameter being monitored. All the sensors continuously communicate the collected data to a central base station. The mode of communication from the sensors to the base station can be in different modes as explained in the next article. This base station transmits the collected data to the internet. Also, this base station continuously analyzes the data for any alerts. If any of the parameters exceed the preprogrammed alert levels, alerts such as email, SMS, voice call etc. will be generated to the operators.

Types of real time remote temperature monitoring systems

Based on the technology of the device there are different types of monitoring systems as explained below:
Ethernet-based real-time monitoring systems
The sensors are connected to an Ethernet system through CAT6 cables and connectors, just similar to connecting a computer, printer etc. You will need to have Ethernet ports near to each sensor. These can be powered from an electrical plug or can be POE type (Power over Ethernet). There will not be a separate base station, but a computer in the network can act as the base station.
WiFi communication based real time remote temperature monitoring system
Here there is no Ethernet cabling required. The communication between the sensor and the central station takes place through WiFi routers used for connecting all other computers. The WiFi communication needs power and if you need continuous data transmission, you may have to go for sensors which are powered through an AC supply. There are devices available which continuously collect data and stores in itself and transmits the data only once or twice in a day. Such systems can work on its own battery for a long duration since it is connecting to WiFi only once or twice in a day.
alarm screen remote monitoring system
In this case also there will not be a separate base station, but a computer in the network can act as the base station. The communication reliability depends on the strength and range of the WiFi router.
Radio Frequency based real-time remote temperature monitoring system
These work on Radio frequency. While selecting a device you have to check that the device works on the radio frequency approved by the local authorities. The supplier has to take approval for the device from the authorities. These devices have a comparatively long range of communication from the base station. The base station acts as a receiver and the sensors act as transmitters. There will be continuous interaction between the sensors and the base station.
Such sensor operates with a very low power requirement and hence can have a long battery life without supporting power supply.
