This MQ-2 Gas Sensor is a elelctronic Sensor that detect the concentration of gases in the air, including LPG, Propane, Methane, hydrogen, Smoke and carbon Monoxide. it has a sensing material thath change resistance when it comes into contact with the gas. this change in resistance value is used for gas Detection. MQ-2 is a gas sensor made of metal oxide Semiconductors. the sensor's Voltage divider network is used to measure gas concentrations in the gas. This sensor operates on a 5v DC power Supply. it can detact gases with concentrations rangeig from 200 To 10000 PPM.
