· Sensitive material of MQ2 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.
MQ2 gas sensor has high sensitivity to propane and smoke, also can detect the natural gas and other flammable steam well. It is with low cost and suitable for different applications of detecting kinds of flammable gases. It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector.

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 ...
