Introduction: The gas sensing material used in MQ-5 gas sensor is two tin oxide (SnO2), which is lower in clean air.. When there is combustible gas in the environment, the electrical conductivity of the sensor increases with the increase of the combustible gas concentration in the air.. The change of electrical conductivity can be converted to the output signal corresponding to that of the gas concentration by using the simple circuit.. The sensitivity of MQ-5 sensor to propane, propane and methane is high, and the methane and propane can be well considered.. This sensor can detect a variety of combustible gases, is a low-cost sensor for a variety of applications.
