This shows the typical sensitivity characteristics of the MQ-4. Rs means re-

sistance of the sensor in dierent gases, Ro means resistance of sensor in

1000ppm Methane

Correlation between sensor resistance and the ambient temperature and

air humidity

The resistance of the sensor can be calculated with the following formula:

Rs=(Vc/VRL 1)×RL -

VC= Supply voltage; VRL= voltage analog pin;
