Thermopile Sensor MRT-313

  • MRT-313(1).png


MRT-313 sensor is a thermopile temperature sensor, which is formed by connecting hundreds of pairs of thermocouples in series based on MEMS technology. According to Seebeck's 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.


* TO-39 package; specific viewing angle
* Fast response; good stability
* High NTC accuracy
