Alcohol Sensor Module (MQ3) depth acts as a variable resistorIntroduction: Alcohol Sensor(MQ3) module is useful for gas leakage detection (in home and industry). It is suitable for detecting Alcohol, Benzine, CH4, Hexane, LPG, CO. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by using the potentiometer. Features: Detection Gas: Alcohol Gas Concentration: 0. 4mg L 4mg L Heater Voltage: 5. 0V Load Resistance:
