Hey Guys, In this tutorial I'm going to show you How to use the MQ2 Gas Sensor in an easy way.
The MQ-2 is a smoke and combustible gas sensor. It can detect flammable gas in a range of 300 - 10000ppm. Its most common use is domestic gas leakage alarms and detectors with a high sensitivity to propane and smoke. This type of smoke sensor is made of a tin oxide semiconductor gas sensing material.
