Alcohol Click Board
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.
