Smart Three Layer Anti-theft Vehicle Security System Based on Arduino Microcontroller

Abstract

Substantial increase in vehicle theft calls for a robust vehicle security system which can offer real time monitoring and control. In this paper, an efficient and low cost anti-theft security system based on Arduino Uno microcontroller is proposed. This system has three layers of protection. The first and second protection works in such a way that, when a person tries to steal the vehicle, the vibration sensor and sound sensor present on board, when exceeded some predefined value, will trigger the microcontroller to operate the relay driver which controls the engine ignition system of the vehicle, and will make the vehicle stop immediately. The third and last protection system works when the first and second system fails to operate and the thieve gets away with the vehicle, then one can both monitor and control the vehicle remotely using a smartphone, through the GPS and GSM technology present on board the system.
