The Analog Gas Sensor(MQ2) module utilizes an MQ-2 as the sensitive component and has a protection resistor and an adjustable resistor onboard. The MQ-2 gas sensor is sensitive to LPG, i-butane, propane, methane, alcohol, Hydrogen and smoke. It could be used in gas leakage detecting equipment in family and industry. It takes a short time to heat up in order to work correctly. The resistance of the sensitive component changes as the concentration of the target gas changes. It has a high sensitivity and fast response time and the sensitivity can be adjusted by the potentiometer.
