InDepth: How MQ2 Gas/Smoke Sensor Works? Interface it ...

+

MQ2 is one of the commonly used gas sensors in MQ sensor series. It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as Chemiresistors 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. MQ2 Gas sensor works on 5V DC …

MQ2 Gas Sensor Working Principle Its Applications

+

This sensor is also used for Air quality monitoring, Gas leak alarm and for maintaining environmental standards in hospitals. In industries, these are used to detect the leakage of harmful gases. Some of the alternatives of the MQ2 gas sensor are MQ6, M306A, AQ3 sensors. To detect which gas have you used the MQ2 Gas sensor?
