· 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.
datasheet. In order to convert the digital signal to concentration units, the datasheet chart is used again. A simple calibration line has y = mx + b, however, the MQ-2 gas sensor is not linear. It follows a log-log scale so a bit more calculation is needed. So the y = mx + b equation can be converted to log(y) = m*log(x) + b. Now using the chart, the slope and intercept can be calculated ...
