Thermopile sensors are designed to measure temperature from a distance by detecting an object''s infrared (IR) energy. The higher the temperature, the more IR energy is emitted. The thermopile sensing element, composed of small thermocouples on a silicon chip, absorb the energy and produce an output signal. A reference sensor is designed into the package as a reference for compensation ...

Here an operational amplifier (opamp) of LM 339 is used as a comparator circuit. When the IR receiver does not receive a signal, the potential at the inverting input goes higher than that noninverting input of the comparator IC (LM339). Thus the output of the comparator goes low, but the LED does not glow.
