Add a high-sensitivity alcohol gas sensor to your design with the addition of Alcohol click. The board incorporates a MQ-3 high-sensitivity alcohol sensor to detect alcohol concentration. Made of an inorganic compound called Tin dioxide (SnO2), the gas sensing layer on the MQ-3 sensor unit has lower conductivity in clean air. However, the sensitivity rises as the levels of alcohol gas rise.

Alcohol click features a small potentiometer for calibration that enables the user to set its own scale and adjust the load resistance of the sensor circuit. Using the AN (OUT) mikroBUS line, Alcohol click communicates with the target board. This board is designed to use 5V power supply only.

It offers very good sensitivity and fast response to alcohol gases, and is designed to detect presence of alcohol in concentrations from 0.04 to 4mg/l. It makes an ideal choice for portable alcohol detector and breathalysers for estimating BAC (blood alcohol content).

IC/Module: MQ-3 Semiconductor Sensor

A semiconductor sensor for alcohol detection, MQ-3 exhibits fast response and high sensitivity to alcohol gas in the air. It has a wide detection range (from 0.04 to 4mg/l) and outputs its reading as an analog voltage. However, it is also suitable for different applications.

High Conductivity under Presence of Alcoholic gas

The MQ-3 alcohol sensor aboard Alcohol click has a Tin dioxide (SnO2) gas sensing layer, which shows low sensitivity in clean air. The sensor conductivity increases as the levels of alcohol gas rise.

Sensor Calibration for the Environment

A small, onboard potentiometer allows the user to adjust the load resistance of the sensor circuit according to the environment it is used.
