Vehicle theft remains a significant concern worldwide, especially in urban areas where vehicle density is high and traditional security systems are often insufficient. This project presents a cost-effective and intelligent Vehicle Theft Protection System that enhances vehicle security through biometric authentication and real-time user intervention using GSM communication. The core of the system is built around the Arduino UNO microcontroller, interfaced with a fingerprint sensor module (R305S), a GSM module (SIM800L), and a relay module to control the ignition system. Authorized users register their fingerprints in the system memory. Upon an unauthorized access attempt, the system sends an SMS alert to the vehicle owner, who can remotely allow or deny engine start. The proposed system provides a high-speed, reliable, and cost-effective solution for automotive embedded security applications.
