Alcohol Click Board

Add a high-sensitivity alcohol gas sensor to your design with the addition of Alcohol Click Board™. The board incorporates an 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. The Alcohol Click Board™ 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 Board™ communicates with the target board. This board is designed to use a 5V power supply only. It offers very good sensitivity and fast response to alcoholic gases and is designed to detect the 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)..
