Introduction
This analog gas sensor MQ2 is used in gas leakage detecting equipment in both consumer electronics and industrial markets. This sensor is suitable for detecting LPG, I-butane, propane, methane, alcohol, Hydrogen and smoke. So the detecting scope of this sensor is very wide and it has high sensitivity and quick response. In addition, the sensitivity can be adjusted by rotating the potentiometer on the sensor.
