MQ2 Reading different gases Sensors Arduino Forum

06/05/2021· MQ2 Reading different gases. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000.
