Specifications

 

How Does the GPRS Temperature Logger CWT5016 works?

The GPRS Temperature Logger CWT5016 equipped one reliable GPRS Module inside, and plus one sensitive temperature sensor, the sensor has a predictable resistance that is affected by temperature change, so as the temperature increases or decreases the electrical current changes, or the resistance increases and decreases. Then transmits the electrical signal to MCU, and the MCU will process the signal and then transmits to Monitoring Center Domain or Sever by GPRS.

 

Once the Monitoring Center Received the data, will identify the data and distinguish where is from, then store it and display them as line chart as well as show the place by map for user review. More about the Web Based monitoring center please see GPRS Temperature Logger Web Based Monitoring Center Datasheet.
