Thermopile sensor
Application:
Non-contact temperature measurementProduct characteristics:
TO-46 package1. Description
GT-117 sensor is the thermopile temperature, based on MEMS technology to connect hundreds of pairs of thermocouples in series. It uses the Seebeck principle. When there is a temperature difference between the target and the environment, the sensor outputs a corresponding voltage to detect the presence of the target or the temperature of the target.
