A new breath alcohol detector for a driver has been developed. A mouthpiece is not required for the detection because driver’s breath sample is captured by an electric suction fan of the detector. The influence of an arbitrary dilution of driver’s expiration is extremely reduced by the calibration of alcohol concentration, using an oxygen level of driver’s expired breath that is measured simultaneously with the alcohol content. The detector is able to measure breath alcohol concentration rapidly and easily, compared with the current breath alcohol detectors, which require a blowing through a mouthpiece. Good accuracy has been demonstrated in an experiment with the drunk subjects.
