    Sensitive material of  MQ-4 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist the sensors conductivity increases higher along with the gas concentration rising.

    MQ-4 gas sensor has high sensitivity to Natural gas, Methane and could be used to detect both Methane and Propane. The sensor could be used to detect different combustible gas especially Methane, its low cost and suitable for different application.
