mq2 gas sensor Arduino
The MQ2 gas sensor can easily detect smoke, liquefied natural gas (LNG), butane, propane, methane, alcohol, and hydrogen in the air.MQ2 Gas sensor is a Metal Oxide Semiconductor (MOS) type Gas Sensor mainly used to detect gases like Methane, Butane, LPG, Smoke, etc. It is also known as Chemiresistors as the gas detection is based on the change of resistance of the sensing material when the Gas comes in to contact. #shorts #arduinoproject
