Gas Sensor Module MQ-2


It can detect:?H2, LPG,CH4,CO,ALCOHOL


MQ-2 is one of the commonly used gas sensors in MQ-2 sensor series. It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as resistors as the detection is based upon change of resistance of the sensing material when the Gas comes in contact with the material. Using a simple voltage divider network, concentrations of gas can be detected.
