· I copied one curve from the MQ2 datasheet : Along the horizontal axis you see the values 100, 1000 & 10000. Between 100 & 1000 each vertical line adds 100, between 1000 & 10000 each vertical line adds 1000. On the vertical axis it works just the same: each horizontal line between & 1 adds , between 1 & 10 it adds 1. So the first H2 lies at (200,2) Reply Quote 0. 1 Reply Last reply ...

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 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 ...
