Home security system based on PIC18F452 microcontroller

We used PIC18F452 microcontroller for hardware and software implementation of our home security system design. Based on PIC18F452, our system can monitor doors and windows of a house and can set alarm and warming signal to a nearest police station if anybody tries to break in. This security system also provides the functionality to identify the residents ID card to get access to the house without turning on the warning signal and alarm. Also, the security system provides a status that is not monitoring the door and windows since there is some possibility that the host do not want the system always checks the status of their house.
