Netvox Wireless 2-Gang Thermocouple Sensor -High Temperature - R718CT2 is used to detect temperature of the object and medium which thermocouple is contacted. It can be connected to two thermocouples for testing. It uses SX1276 wireless communication module.

R718CK2 is connected with type T thermocouple, it supports good temperature accuracy operation. The collected data is displayed in the gateway.

Principle of Operation

The thermocouple is processed by the ADS1118 chip ADC for ADC sample conversion, and the ADS1118 communicates with the module via SPI.


Example Applications

  • Low to Med Temperature Measurement
  • Freezer, Fridge System Equipment
