Technical data thermopile sensors - Mantech Electronics

The thermopile output follows the already known law according Equ. (3a). Because thermopile signals are usually in the range of millivolts, they need amplification by a very low noise and low offset operational amplifier (OpAmp). The output signal simply multiplies by the amplification fac-tor A. ϑ I A ATh TP Comp ' = ⋅⋅ε⋅()−4−δ ...

Thermopile - Wikipedia

A 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 a device works on the principle of the thermoelectric effect, , generating a voltage when its dissimilar metals (thermocouples) are exposed to a temperature difference.
