LPGSmokeAlcoholPropaneHydrogenMethane, and Carbon Monoxide Sensor

SKU: 0040 Category:


Give your next Arduino project a nose for gasses with the MQ2 Gas Sensor Module. This is a robust Gas sensor suitable for sensing LPGSmokeAlcoholPropaneHydrogenMethane, and Carbon Monoxide concentrations in the air. If you are planning on creating an indoor air quality monitoring system; breath checker or early fire detection system, MQ2 Gas Sensor Module is a great choice.

MQ2 is one of the most commonly used gas sensors in the MQ sensor series. It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as Chemiresistors as the detection is based upon a change of resistance of the sensing material when the Gas comes in contact with the material. Using a simple voltage divider network, concentrations of the gas can be detected.

MQ2 Gas sensor works on 5V DC and draws around 800mW. It can detect LPGSmokeAlcoholPropaneHydrogenMethane, and Carbon Monoxide concentrations anywhere from 200 to 10000ppm.
