This MQ-3 Alcohol Detector Gas Sensor Module is simple to use.
MQ-3 Alcohol Detector Module which can sense the presence of Alcohol in the air. The module uses our MQ-3 sensor.
It simplifies the interface to the odd pin spacing of the sensor and provides an interface through standard 4 x 0.1. header pins.

It provides an analog output corresponding to the concentration of the gas in the air and an easy-to-use digital output.

The onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered.
Perfect sensing alcohol concentration on your breath just likes a common breathalyzer.
Just power the module with 5V set the threshold and you can start getting the gas concentration of the air around the sensor! An onboard LED signals the presence of any gas.

The digital output can be easily interfaced to microcontrollers and other circuits. The analog output can be hooked up to an ADC of a microcontroller to get a wide range of sensor readings.
