Gas Analog CH4 Gas Sensor MQ4 For Arduino. The MQ sensors are one of the most commonly used gas sensors. One of those is the MQ4, which is sensitive to CH4 (Methane), Natural Gas, and LNG (Liquefied Natural Gas). Once connected with an Arduino board, it needs a little time to heat up. Through its potentiometer, the sensitivity is adjustable.

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.

20210506· Regardless of the details, no sensor will give reliable measurements without careful calibration. Those cheap sensors are not reliable and also not stable, so they have to be calibrated frequently to be of any use at all. To do that calibration you need an accurate, calibrated sensor, which calls into question the reason for using the MQ series at all. You [u]certainly would not want to use ...
