How a thermopile works
WebThermopile Sensor Physics. Thermopile sensors are based on thermocouples. A thermocouple consists of two dissimilar metals connected in series. To detect radiation, one metal junction is typically blackened to absorb the radiation. The temperature rise of this junction with respect to another non-irradiated junction generates a voltage. WebA thermopile is an electronic device that converts thermal energy into electrical energy. It is composed of several thermocouples connected usually in series or, less commonly, in parallel. Such a device works on the principle of the thermoelectric effect, i.e., generating a voltage when its dissimilar metals (thermocouples) are exposed to a ...

WebBasically, a thermocouple consists of two wires made of different metals joined in two places. Heat enters at one end, splits, travels down each wire separately, then rejoins. When it rejoins, it creates electricity. The voltage of the electricity gives an accurate reading of a temperature between the ends of the device.
