SAFETY AND SECURITY OF THE PERSONAL BELONGINGS USING MICROCONTROLLER

Abstract

Security systems are vital for protection of information and property which it is necessary for prevention them from theft or crime. The simplicity of design makes it compatible in different scenarios such as a home or commercial security system like datacenters and banks. In this experimental work it has been programmed the microcontroller 89C51, and connected it with other electronic components to economize a security of money cabinet. The assembly language was used to program this microcontroller to control for open and close operations of the money cabinet by using limited keys as password of known person. The alarm light emitting diode LED would light by pressing the false key then the camera would take the picture for this unknown person.
