MQ-3 is an Alcohol Sensor which detects alcohol in the air. The MQ3 Gas Sensor Module has both Digital and Analog Output pins. The Digital Output will go high when the alcohol content in the air is above set limit. This limit can be set using the potentiometer on the module. The Analog pin can help us approximate the level of alcohol present in the air.

The sensor operates at 5V and is more commonly used in breath analysers. Along with Alcohol the sensor is also slightly sensitive to Benzine.
