GENERIC Alcohol Sensor MQ3
The MQ-3 alcohol sensor is a gas sensor widely used for detecting alcohol vapors in the air. Its core function relies on a semiconductor gas sensor to measure the concentration of alcohol present. This sensor operates based on the principle of varying electrical conductivity in response to the presence of alcohol molecules. When exposed to alcohol vapors, the sensor's resistance changes, producing an electrical signal proportional to the concentration of alcohol detected. This signal can be interfaced with microcontrollers or other electronic devices for further processing or triggering alarms. The MQ-3 sensor is commonly employed in breathalyzer devices, automotive applications, and various safety systems where detecting alcohol presence is crucial. Its compact size, low power consumption, and reliability make it a preferred choice for alcohol detection across different industries, including automotive safety, industrial safety, and law enforcement.
