This paper addresses the critical need for enhanced road safety by preventing drunk driving through automated vehicle immobilization. It also enables real-time GPS tracking for better vehicle monitoring and swift response in emergencies. By integrating IoT, it ensures remote access to safety data, promoting smarter and safer transportation systems. This project proposes a Smart Vehicle Immobilization System with Integrated Alcohol Detection and Real-Time Gps Monitoring. This system presents a Smart Vehicle Immobilization System with integrated alcohol detection and real-time GPS monitoring. At its core is an Arduino Uno (ATmega328P), interfaced with various sensors and modules to ensure safe and controlled vehicle operation. The MQ-3 sensor detects the driver’s alcohol level, and if it exceeds a predefined threshold, the system immediately initiates a vehicle immobilization process. A GPS module enables real-time location tracking, providing vital data for monitoring and safety. The MPU6050 sensor monitors motion and orientation, adding further vehicle stability analysis. The data is processed by the Arduino Uno and displayed on an LCD screen. The Node MCU Wi-Fi module ensures IoT integration, transmitting information such as alcohol levels and motor status to a cloud-based platform for remote access. A relay driver controls an electronic relay, which, when triggered, deactivates the vehicle’s DC gear motor to prevent operation under unsafe conditions. A buzzer alerts nearby individuals when alcohol is detected. This integrated system ensures that vehicles remain safe and non-operational in high-risk situations, enhancing road safety. Through IoT connectivity, it offers enhanced monitoring and control capabilities, making it a comprehensive solution for smart transportation safety management.
