Nowdays there are many security technologies and many objects get digital security. Big areas are guarded by fences but it is easy to damage and climb over it. Because of this additional protection is needed but we can’t use expensive devices along a long fence (like cameras), they also have to be supplied with a lots of energy. Because of this, it is necessary to develop a device that solve this problem. It is a half a price like cameras. It has a solar cell supply, so it doesn’t need any power supply cable. It has a rechargeable battery that can store the energy for a longer time. It has a built-in radio so it can send messages over the air, and it can reach the office and alarm the guard. This device can detect the movements of the fence.
The hardware consinst of the CC430 ultra low power microcontroller and its peripheral. It consist of a memory, gyrsoscope, battery charger, level converter, a radio, accumulator, solar cell.
