This device is capable of distinctively detecting the saturated water vapor from human breath and accurately measuring alcohol level within 3 seconds once a driver exhales breath onto the device. Hitachi and Honda jointly collaborated on this technology development in an effort to create the ideal alcohol detector.
They also developed a system that can show the alcohol level measured by the detector on the vehicle’s display panel. It can become an ignition interlock to stop a vehicle starting its engine when it detects a driver under the influence of alcohol.
