The MQ2 gas sensor is one of the most widely utilized in the MQ sensor series. It's a Metal Oxide Semiconductor (MOS) type Gas Sensor, also known as Chemiresistors because the detection is dependent on a change in the sensing material's resistance when the gas comes into contact with it. Gas concentrations can be sensed using a simple voltage divider network.
