Abstract In order to prevent drunk driving timely and protect personal safety, a
kind of vehicle-loaded alcohol concentration detector based on single chip
microcomputer control is designed. The detector usesAT89C51 microcontroller
as the core, makes use of the gas sensor, A/D converter to detect the alcohol
concentration of the breath of the driver, can set different thresholds according to
the space of the car model, automatically cut off the ignition circuit for the
exceeded threshold, and has the sound and light alarm function, which
fundamentally solve the problem of drunk driving. The instrument is compact in
size, stable in performance, convenient… More >
