MRT-511
Product Description
MRT-511 Thermopile temperature sensor
Product description
MRT-511 type sensor is a thermopile temperature sensor, based on MEMS process, hundreds of thermocouples are connected in series. Using Seebeck's principle, when there is a temperature difference between the target and the environment, the sensor outputs a corresponding voltage, thereby detecting the presence or temperature of the target.
