  • Good sensitivity to a wide range of combustible gases.

  • High sensitivity to Natural gas.

  • Long life and low cost.

  • Simple drive circuit.

  • High sensitivity to alcohol.
    • This is a simple-to-use compressed natural gas (CNG)sensor, suitable for sensing natural gas concentrations in the air. The MQ-4 can detect natural gas concentrations anywhere from 200 to 10000ppm.It has high sensitivity and fast response time. 

    • The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.
    • The sensitive material of the MQ-4 gas sensor is SnO2 which has lower conductivity in clean air, in the presence on CNG, the conductivity of the sensor rises proportionally with the amount of CNG. 
    • The 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.MQ-4 gas sensor has high sensitivity 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 application.


    • Domestic gas leakage detector 
    • Industrial Combustible gas detector 
    •  Portable gas detector
