Development of a Driver Safety Monitoring Device with Ignition Interlock

Abstract

Drunk driving and falling asleep on the wheel are the most prevalent causes of car accidents. We cannot ban individuals from consuming alcohol, but we can reduce the number of accidents by monitoring who is drinking and embedding safety devices in the car to ascertain that no one drinks and drives, and as well warn the driver if he or she falls asleep behind the wheel. This embedded safety system consists of an alcohol sensor, infrared sensor, motor, buzzer, and other devices that are all linked to the core microcontroller unit. An eye blink sensor was utilized to detect sleep by establishing a time limit; When the driver falls asleep. The system alerts him. The alcohol sensor detected whether or not the motorist is intoxicated. When he or she was too inebriated, the car issued a warning and the engine shuts down. Likewise, when the IR sensor detected tiredness in the driver or the alcohol sensor detected alcohol, the system notified the driver via buzzing sounds and a message on the Liquid Crystal Display (LCD) and the ignition locked further slowing the vehicle when the driver failed to respond to the alarm. The adoption of this embedded technology guarantees a method for monitoring a driver's tiredness and alcohol levels, thereby preventing car accidents before they occur.
