How to Use MQ-4 Methane Gas Sensor - Arduino, Raspberry Pi ...

2020-09-11· MQ-4 Methane Sensor Overview. At the heart of the MQ-4 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.
