Abstract:
This project is aimed to implement a system that will automate the security system of a given area. It ensures that the user is alerted each time an intruder encroaches a secured position in an area of application through the sounding of alarm.(Siren) More so, information about the intruder’s position will also be made noticed to the user by this security system. The Project will be based on microcomputer and other electronic design to achieve the above stated purposes. The interfacing medium will make use of parallel port. The sensors (Light Dependent Resistor and LEDS) will receive the signal when the intruder is around while the control program will translate the received signal from the sensors to useful information about the function of the system.
