In contemporary times, a significant portion of accidents on the road can be attributed to the perilous practice of driving under the influence of alcohol. In response to this pressing issue, we have embarked on a groundbreaking project designed to curtail such accidents. This project employs cutting-edge technology to detect alcohol consumption by drivers through the analysis of gaseous substances present in their breath. Central to our project is the use of sensors strategically placed on the steering apparatus of the vehicle, precisely where the driver's breath is directed. These advanced sensors are adept at quantifying the alcohol content in the driver's breath. Should the alcohol level surpass a predefined threshold, the system will promptly issue a command to immobilize the vehicle's engine, rendering it inoperable. The significance of our work lies in its potential to substantially diminish the frequency of accidents stemming from alcohol impairment. By implementing an innovative system that seamlessly integrates alcohol detection with engine locking, we aim to drastically reduce the instances of accidents associated with drunk driving. In essence, our project stands as a formidable solution in the ongoing battle against alcohol-related accidents, offering a technologically advanced means of enhancing road safety and safeguarding lives.
