MQ 2 Gas Sensor IoCT

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 MQ2 gas sensor is not linear. It follows a loglog 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 ...
