Development of Alcohol Detection with Engine Locking and Short Messaging Service Tracking System

Road travelling is among the simplest modes of transportation. Accidents are frequently the consequence of a human error on the road, and they can occasionally be brought on by alcohol intake which alters the victim's way of thinking. Law enforcement agencies have made significant efforts to lower the risk of drunk driving, but none have been able to significantly diminish it. Due to this, the proposed system was developed to lessen the likelihood of accidents on our roads being brought on by intoxicated drivers. The device can prevent a drunk driver from operating the vehicle and, in the event of an accident, send a message to a pre-programmed number informing it of the location of the vehicle. The entire software is built around a microcontroller, an alcohol sensor, and a vibration sensor. The sensor is used to set an alcohol threshold at which an alarm will buzz, and when the set threshold is exceeded, the flow of fuel to the engine will cease, thereby bringing the car to a halt. In case of an auto crash, the microcontroller would receive input from the attached vibration sensor, and send the location of the vehicle to a pre-registered phone number on the subscriber identification module (SIM) of the project. This project is a prototype of what is proposed in a vehicle where the DC motor serves as the fuel pump.
