This document describes an ARM-based vehicle theft control, positioning, and collision detection system. The system uses accelerometer, GPS, GSM, and fingerprint sensors with an ARM controller to detect vehicle accidents and theft. In the event of an accident, the system detects abnormal vehicle movement with the accelerometer and notifies emergency contacts by sending SMS messages with the vehicle's GPS coordinates. For theft prevention, the system requires fingerprint authentication and sounds an alarm if unauthorized fingerprints are detected, also sending SMS alerts. If the vehicle is stolen, owners can track its live location using the GPS module. The system aims to provide quick emergency assistance in accidents and increase vehicle security against theft.
