The MQ-3 Alcohol Sensor Module is a gas detection sensor designed primarily for detecting alcohol and ethanol vapors in the air. It is commonly used with Arduino, ESP32, Raspberry Pi, and other microcontroller platforms for alcohol detection and monitoring applications.
The sensor provides an analog output that changes according to the detected alcohol concentration. Many MQ-3 modules also include a digital output with adjustable sensitivity, allowing you to set a detection threshold for simple alarm or indication projects.
