This document describes a proposed vehicle security system using IoT technologies. The system uses several sensors and devices to enhance vehicle security and safety. It includes a fingerprint sensor for biometric door locking to prevent theft. An IR sensor is used to detect obstacles near windows to close them automatically. An ultrasonic sensor measures distance to obstacles to avoid collisions. A GPS device tracks the live location of the vehicle. The system only allows the engine to start if the driver is wearing a seatbelt for safety. It aims to address disadvantages of existing systems and provide enhanced security, safety and monitoring features through IoT technologies like sensors, microcontrollers and mobile apps.
