How to Use MQ-4 Methane Gas Sensor | Microcontroller Tutorials

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.

Gas Sensors Methane -

Methane is a gas produced by a group of colonic anaerobes. All methane produced by human beings is a metabolic product of intestinal bacteria, and about 50% of it is excreted. Methane is also found below ground and under the sea floor. It is emitted during production and transport of coal, natural gas, and oil, as well as from lifestock. Methane makes up roughly 10% of Greenhouse Gas ...
