Wireless Security System with Password Protection

Abstract

Home security is not minor issue because crime is increasing and everyone wants to take proper measures to prevent invasion [1]. In this paper, design and implement of a microcontroller based wireless security system with password protection have been presented and analyzed. Microcontrollers with other peripheral devices which include Liquid Crystal Display (LCD), Buzzer, Sensors, Encoder and RF Module are responsible for reliable operation of the proposed security system. In addition, the system is provided with a manual keypad which provides a password protection in order to provide extra security to the system. Assembly language is used as the programming language and Atmel is used to compile the code in order to design a program that controls the system along with maintaining all security functions.
