  • Sensitive material of MQ-4 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-4 gas sensor has high sensitity to Methane, also to Propane and Butane. The sensor could be
    used to detect different combustible gas, especially Methane, it is with low cost and suitable for different


  • High sensitivity to Combustible gas in wide range
