Mrt-311 thermopile temperature sensor
The mrt-311 sensor is a thermopile temperature sensor. Based on MEMS technology, hundreds of thermocouples are connected in series. Based on the Seebeck principle, when there is a temperature difference between the target and the environment, the sensor outputs the corresponding voltage to detect the temperature of the target.
