Product Overview

MIKROE Alcohol Click has a high sensitivity to alcohol and it can be used to detect alcohol in concentrations from 0.04 to 4mg/l.

Alcohol Click carries an MQ-3 Semiconductor sensor for alcohol. The Click is designed to run on a 5V power supply only. It communicates with the target microcontroller through the AN pin on the mikroBUS™ line.

MQ-3 sensor features

The gas sensing layer on the sensor unit is made of Tin dioxide (SnO2), an inorganic compound which has lower conductivity in clean air. The conductivity increases as the levels of alcohol gas rise.

Calibrating the sensor

To calibrate the sensor for the environment you’ll be using it in, Alcohol Click has a small potentiometer that allows you to adjust the Load Resistance of the sensor circuit.
