Most breathalyzers work by measuring compounds in your breath using one of three technologies: Semiconductor sensors detect changes in electrical current when alcohol molecules are present (common in personal breathalyzers) Fuel cell technology creates an electrochemical reaction with alcohol (used in police and professional devices) Infrared spectroscopy measures how alcohol molecules absorb infrared light (found in advanced testing equipment) The critical limitation is that these devices aren't always detecting ethanol (drinking alcohol) specifically
