MQ6 Gas Sensor Module has a high sensitivity. It has a fast response time. The gas sensor output is an analog resistance. The drive circuit is very simple and all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

Sensitive material of MQ6 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.

MQ-6 gas sensor has high sensitity to Propane, Butane and LPG, also response to Natural gas. This gas sensor module could be used to detect different combustible gas, especially Methane, it is with low cost and
suitable for different application.
