MQ3 Alcohol Sensor Module

MQ3 Alcohol Sensor Module is made using Alcohol Gas Sensor MQ3. It is a low-cost semiconductor sensor that can detect the presence of alcohol gases at concentrations from 0.05 mg/L to 10 mg/L. The sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air. Its conductivity increases as the concentration of alcohol gases increases. It has a high sensitivity to alcohol and has good resistance to disturbances due to smoke, vapor, and gasoline. This module provides both digital and analog outputs. MQ3 alcohol sensor module can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi, etc.

This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has high sensitivity and a fast response time. The sensor provides an analog resistive output based on alcohol concentration.
