NDIR Thermopile-Based Gas Sensing Circuit

CIRCUIT DESCRIPTION The thermopile sensor is composed of a large number of thermocouples connected usually in series or, less commonly, in parallel. The output voltage of the series-connected thermocouples depends on the temperature difference between the thermocouple junctions and the reference junctions. This principle is called the Seebeck effect. The circuit uses the . AD8629. op …
