Cold Chain Environment Sensor: DTPHHR1000

The Cold Chain Environment Sensor is a portable handheld reader, which monitors and displays carbon dioxide, temperature and relative humidity levels on the local display. The data will be logged in the memory with time and date stamp which can be downloaded to the PC through USB port and also can be transmitted to the central server through GPRS.

The Cold Chain Environment Sensor has inbuilt RFID reader, which used to identify and record the location where carbon dioxide, temperature and relative humidity levels needs to be monitored, this feature is also used to check whether the person has actually visited the place and recorded the data.
