This thesis is targeting to develop and engineer a burglar alarm system prototype using the software and hardware environment Arduino, which is originally manufactured by Smart Projects. The system under development provides a versatile theft inhibition hardware configuration for the holder of the system. It also provides vehicle localization enabling features in case of theft.

In the final project, the aim is not to reach commercial benefit. The aim is to get familiar with software libraries and information offered by Arduino environment, GPS utilizing standard NMEA0183 and SIM900 with AT commands. This project examines burglar alarm system engineering from a commercially neutral point of view. Most of the sources have been published by companies, but without these essential resources it would be extremely complicated to engineer the software. In process of this final project, the functional requirements and hardware are defined. Then the embedded software is implemented. Finally, the achievements are explored and the final outcome is discussed.

With the available resources for the project, it was feasible to create a project plan. The project plan describes how the burglar alarm system should work. A partial software was engineered and it was ready to use few AT commands. Also, the hardware design was put together. The GSM/GPRS Quadband module was assembled into the Arduino Mega 2560, and an anti-theft immobilizer relay was soldered into a circuit board. The PIR-sensor was acquired and connected to the Arduino Mega 2560.
