DIGITAL THERMOPILE SENSORS
Thermopile Sensor Function The thermopile infrared sensor consists of an absorber, which is thermally isolated from a frame and in series connected thermocouples. When the absorber is pointed towards an object with a temperature different from the absorber, then the power emitted by object and absorber differs as well. There is a netto radiative heat flow to/from the absorber which is heating ...
