Alcohol detector

The alarming situation

Driving under the influence of alcohol is one of the major reasons for a large number of fatal traffic accidents every year, all over the world. The situation is improved by legislation and law enforcement.

Sweden is a forerunner, with a low concentration limit of 0.02% blood alcohol concentration, and frequent police controls. Sweden has also pioneered the use of alcolocks in quality assurance of transportation services.

Despite these efforts, approximately 150 Swedes are killed in these types of accidents. A technological leap is needed before alcolocks can be accepted by the vast majority of vehicle drivers.

Paradigm shift within alcohol detection

The KAIA alcohol sensor solution represents a technology breakthrough. New sensor technology, a user-friendly interface – no mouthpiece – no maintenance, and a competitive size and cost form the basis for a true mass-market product.

• Contact free without mouthpiece
• Completely maintenance free
• Unique optical construction
• Reliable
• Hard to manipulate
• Hygienic
• Cost effective
• Fast response time

The KAIA sensor technology works with infrared (IR) spectroscopy, which has superior performance compared to conventional alco-detector devices. The KAIA concept uses contact free measurement
of concentrations of alcohol and carbon dioxide in the drivers’
exhaled air.

A patented optical device using multiple reflections makes it possible to calculate the level of alcohol with high resolution.

The driver blows at a distance of 10-15 centimeters from the
sensor device, which – if the sensor is integrated with the steering wheel – allows for a simple test as soon as the driver is seated in the driver’s seat.
