Sensitive material of MQ-6 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 electro circuit, Convert change of conductivity to correspond output signal of
gas concentration.
MQ-6 gas sensor has high sensitivity to Propane, Butane and LPG, also response to Natural gas. The
sensor could be used to detect different combustible gas, especially Methane, it is with low cost and
suitable for different application.
