GSM Based Vehicle Anti-Theft Device Using Vibration Sensor and Arduino

Theft of two-wheelers is a persistent issue, and thus, effective security systems need to be developed to reduce losses. This paper presents a novel anti-theft device that uses a vibration sensor to enhance the security of two-wheelers. The system detects unauthorized movements or tampering through a highly sensitive vibration sensor integrated with a microcontroller. In case the system identifies some abnormal vibrations, it sets up an alarm to warn the owner, and it is capable of setting up notification over wireless communication technologies. This solution has proved to be cheaper, energy-efficient, and reliable to protect two-wheelers in a better manner without reducing the comfortability of users. Complete testing has proved the accuracy of this system for theft attempts and its possible practicality.
