MRT511 Thermopile Temperature Sensor

TO-46 Package

MRT-511 thermopile sensor is based on MEMS technology, consists of hundreds of thermocouples connected in

series. Using Seebeck principle, when there is a temperature difference between the target and the environment,

the sensor gives the corresponding voltage output, therefore detecting the existence of the target or the

temperature of the target.
