Smart Vehicle Accident and Alcohol Sensing Alert with Engine Locking System
Keywords:

The vehicle accident and alcohol sensing alert with engine locking system is a smart vehicle safety solution designed to reduce road accidents caused by drunk driving and delayed emergency response. This system integrates alcohol detection, accident detection, automatic engine control, and alert mechanisms to enhance overall road safety for drivers and pedestrians. An MQ-3 alcohol sensor is used to continuously monitor the alcohol concentration in the driver’s breath. If the detected alcohol level exceeds a predefined safe threshold, the system immediately restricts engine ignition or disables the running engine, thereby preventing the vehicle from being operated under unsafe conditions. This feature plays a crucial role in minimizing accidents due to alcohol consumption. To detect collisions or sudden obstacles, IR sensors are employed. These sensors help identify accident events in real time by detecting abrupt changes or impacts. The entire system is controlled by a microcontroller, which continuously processes sensor inputs and makes decisions based on programmed safety logic. In the event of alcohol detection or an accident, the system activates a buzzer alert to warn the driver and triggers a communication module to send notifications to emergency contacts or authorities. This ensures quick response and timely medical assistance during emergencies. By combining monitoring, control, and alert functionalities into a single embedded platform, the proposed system significantly enhances vehicle safety, reduces drunk-driving incidents, and ensures rapid accident reporting, contributing to safer roads and improved traffic management.
