alcohol detection

Alcohol detection typically involves measuring the presence of alcohol (ethanol) in a person's breath, blood, or saliva. Breathalyzers are common devices that analyze a person's breath to estimate blood alcohol concentration (BAC). They work by using a sensor that detects ethanol molecules in the exhaled air, providing a quick and non-invasive measurement. More advanced methods may include blood tests, which directly measure alcohol levels in the bloodstream, or saliva tests, which are less common. These detection techniques are used by law enforcement and medical professionals to assess impairment or intoxication levels accurately.
