MQ series sensors Sensors Arduino Forum

May 06, 2021· The MQ sensors are wired up to provide an analog input, which tells you (after calibration) the concentration of gas it is detecting. But it has no idea which gases contributed to that reading. Worse, the sensor may be intended to detect a particular gas or gases, but it may also be influenced by others in addition to those it is designed for.
