Interfacing MQ2 to Arduino- Gas Sensor for Smoke-Butane-CH4 and LPG

In this article, we are going to learn how to interface MQ2 Gas Sensor with Arduino. MQ2 is basically a general purpose gas sensor (similar to MQ5) which can sense a broad range of gases like LPG, Butane, Methane(CH4), Hydrogen and in addition to these gases MQ2 is sensitive to smoke as well. In a previous article, we have wrote a tutorial on Interfacing MQ5 Gas sensor to Arduino. Both MQ5 and MQ2 are basic ...
