20200911· MQ4 Methane Sensor Overview. At the heart of the MQ4 is a heater and electrochemical sensor. When the target gas enters the membrane and reaches the sensor, it undergoes a redox reaction which creates current. This current is stronger for sensors at specific gases. In the case of the MQ4, it’s more sensitive to methane, butane and propane.

The MQ4 is used in gas leakage detecting equipment in consumer and industry markets. This sensor is suitable for detecting CH4, natural gas and Liquefied Natural Gas (LNG). It is also used to avoid exposure to alcohol, cooking fumes and cigarette smoke. Specifications: High sensitivity to CH4, Natural Gas. Small sensitivity to alcohol and smoke.
