MQ3 Alcohol Gas Sensor

Description:

• The MQ3 sensor is its semiconductor sensing component, which reacts to the presence of Alcohol molecules and Brenzine in the air.
• The sensor’s electrical conductivity changes as it comes into contact with alcohol vapors, and this change is then translated into an analog voltage signal.
• By connecting the sensor to an analog-to-digital converter (ADC) on a microcontroller, to obtain digital readings of alcohol concentration.
• Potentiometers on the sensor enable to adjust the sensitivity according to specific requirements.
• The sensor can also be used for creating alcohol leakages preventing systems.
