IoT-Based Smart System for Vehicle Collision Prevention and Alcohol & Gas Detection

This IoT-based intelligent system enhances vehicle safety by detecting potential collisions, alcohol impairment, and harmful gases in real time. It integrates ultrasonic sensors, touch sensors, alcohol detectors, and gas sensors to monitor critical driving conditions. Ultrasonic sensors identify nearby obstacles, alerting the driver to prevent collisions, while a touch-activated alcohol detection system ensures the driver is sober before operating the vehicle. Additionally, a gas sensor continuously monitors hazardous gases like carbon monoxide within the vehicle. The collected data is processed by a microcontroller and transmitted via IoT to a cloud platform or mobile app for remote monitoring and alerts. By proactively identifying risks, this system significantly enhances road safety and promotes a secure driving environment.
