Automatic Alcohol Detection In Car

electronics and telecommunication

The main objective of this system is to design a system for implementing an efficient alcohol detection system that will be useful to avoid accidents. Many different types of accidents occur in daily life. Accidents may cause because of many reasons it may result in brake failure. Most often accidents occur because of an over the drunken person. Though there are laws to punish drunken drivers they can't be fully implemented. Because the traffic police cannot stand on every road to examine every driver whether he/she has drunk or not. This can be a major reason for accidents. So there is a requirement for an effective system to check drunken drivers. Therefore, to avoid these accidents we have implemented a prototype project. This system measures blood alcohol levels from a driver’s breath. The amount would be detected from sensors mounted ahead of the driver. But the driver wouldn’t even have to be compelled to remember they are being monitored this system is equipped with an mq3 sensor, microcontroller, LCD. The mq3 gas sensor is embedded in the steering wheel. An MQ3 gas sensor constantly analyzes the amount of alcohol present in the body of the driver. If the content of alcohol above the prescribed limit is.
