Vehicle Alcohol Test

sensor for Vehicle Alcohol Test

The picture shows a common "ignition interlock system" with an alcohol detection function in the United States. This lock is connected to the ignition system of the car. Before ignition, the driver must perform a blow test. After detecting that the alcohol concentration in the body does not exceed the standard, the car can be started.

For drivers with a history of Drunk Driving, some cars have interlocks installed on them. If the device detects that the driver is drunk, the car will not start.

This "ignition interlock system" (Alcolock) is installed in the socket of the car's ignition and requires the driver to exhale into the alcohol detector before starting the car. If the blood alcohol level exceeds 80 mg per 100 ml standard, then the driver cannot start the car engine.

It is reported that the device has been used in countries such as the United States, Canada, Australia and Sweden, and the EU is also studying the possibility of taking this measure in full.

The alcohol sensors currently developed by Winsen Technology are currently commonly used in fuel cell type (electrochemical type) and semiconductor type. These two types can be manufactured into ignition interlock system or portable breath alcohol testers, which are suitable for on-site use. Compared with the semiconductor type, the electrochemical type alcohol tester has the obvious advantages of good stability, high precision and good anti-interference.
