Mrt-311 thermopile temperature sensor

The mrt-311 sensor is a thermopile temperature sensor, which is based on MEMS technology and consists of hundreds of pairs of thermocouples in series. Using Seebeck principle, when there is a temperature difference between the target and the environment, the sensor outputs the corresponding voltage to detect the existence of the target or the temperature of the target.
