The MQ-3 Alcohol Sensor Module is a highly sensitive gas detection module designed to detect alcohol vapor in the air. It is especially optimized for ethanol and is commonly used in breathalyzer projects, alcohol detection systems, vehicle safety devices, smart monitoring systems, and Arduino-based electronics projects.
The module uses a semiconductor gas sensor that changes its resistance when exposed to alcohol vapor. An onboard comparator circuit converts this change into both analog and digital outputs, making it easy to interface with Arduino, ESP32, Raspberry Pi, STM32, and other microcontrollers.
