How to Use MQ4 Methane Gas Sensor | Microcontroller Tutorials

Sep 11, 2020· 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.
