Alcohol Sensor

An alcohol sensor is a device that detects the presence of alcohol in a person's breath. It works by measuring how much alcohol vapor is in the air exhaled from the lungs, which correlates to their blood alcohol concentration (BAC). This information helps determine if someone is intoxicated, often used in breathalyzer tests by law enforcement or personal devices. The sensor typically contains a chemical or electronic component that reacts with alcohol vapors, producing an electrical signal that indicates the alcohol level. It provides a quick, non-invasive way to assess alcohol consumption.
