The MQ2 sensor is one of the most popular in the MQ sensor family. A MOS (Metal Oxide Semiconductor) sensor is used. Metal oxide sensors are also known as Chemiresistors since the detecting material’s resistance changes when exposed to gases. The MQ2 gas sensor runs on 5V DC and uses around 800mW. It has a detection range of 200 to 10000 ppm for LPG, Smoke, Alcohol, Propane, Hydrogen, Methane, and Carbon Monoxide.
