A theft detection and tracking system for vehicles, especially cars, developed using Arduino. This system is a prototype smart lock for vehicles which can track the location of the vehicle in real time and can jam the ignition on command.
The major components used are:
| S.No. | Component |
|---|---|
| 1 | Arduino Mega 2560 |
| 2 | GPS Module |
| 3 | SMCOM SIM900A GSM Module |
| 4 | 16x2 LCD Display |
| 5 | Membrane Keypad |
| 6 | Relay Module |
| 7 | Lithium Polymer Battery |
The circuit diagram was created using circuito.io. Arduino Mega is the brain of the system, and the GSM module is used for communication with the user via SMS. The GPS module will fetch the location in real time and the relay module will be used to connect the system with the ignition system.

Circuit designing, component testing and simulation of individual components and the prototype circuit was done using Proteus Design Suite.

This system adds an additional layer of security to the vehicle by password locking the ignition system of the vehicle. Whenever the ignition is to be turned on, this system will ask for a passowrd, and will grant access if the correct password is entered. However, when incorrect password is entered, this system will not allow the ignition to be turned on and will notify the owner the current location of the vehicle via SMS, hence, saving from theft.
