The gas sensing material used in the MQ-2 gas sensor is tin dioxide (SnO2) with lower conductivity in clean air. When there is a flammable gas in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of flammable gas in the air increases. The change in conductivity can be converted to an output signal corresponding to the gas concentration using a simple circuit. The MQ-2 gas sensor is highly sensitive to liquefied gases, propane and hydrogen, and is also ideal for the detection of natural gas and other combustible vapors. This sensor detects multiple flammable gases and is a low-cost sensor for a wide range of applications.
