Abstract

A novel detector of breath alcohol for a driver has been developed. The detector has three features. A mouth piece is not required because driver's breath is introduced to the detector by a suction pump. The influence of fluctuations of driver's breath flow is extremely reduced by the calibration of alcohol concentration using a humidity change. The detector is able to measure breath alcohol concentration rapidly, and the measurement time is about 2 to 3 seconds. The excellent performance have been demonstrated both in breath alcohol simulation tests and in a drunken persons test.
