Air quality gas sensor module
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.
Comparator circuit on board, potentiometer adjusts gas comparison threshold, RL = 453Ω
AOUT: analog output; DOUT: digital output; VCC: supply voltage
Package include: 1 X Air quality gas sensor module
