Air quality gas sensor module consists of a metal oxide semiconductor gas-sensitive layer and a heater. In a gas-testable environment, the conductivity of the sensor increases with the gas concentration, and the internal circuit can convert the change in conductance into an output signal corresponding to the gas concentration. TGS2600 air quality gas sensor, AOUT: analog output; DOUT: digital output; VCC: supply voltage Comparator circuit on board, potentiometer adjusts gas comparison threshold, RL = 453Ω Air quality gas sensor module
