How to measure CO2, Ammonia and Detect Smoke using MQ135 - Arduino …

05/05/2021· I had plans on using MQ4,6,7,9 and 135 together. If you apply a best-fit regression to each response curve, you get the idea how each gas sensor interelates. That's why there are several MQ gas sensors. They sense each gas at a different gradient to concentration. If you are handy with calculus, which I am not, you could figure out a way to get several sensors to induct which gas is high and …
