DESIGN AND IMPLEMENTATION OF AN INTEGRATED ELECTRONIC SECURITY SYSTEM

Abstract

Insecurity can lead to loss of lives and properties in our society. Consequently, the microcontroller deployment to improve security and control took centre stage when threats to engineering equipment such as machines, telecommunication devices, electronic devices and ammunition warehouses became imminent. This paper deals with design analysis and implementation of an integrated electronic security system to aid in securing infrastructures. The objectives are: to optimise a security lock with minimal cost when compared with mechanical locks, design and implement a locking mechanism which gives genuine users the privilege to have access to their premises and also provides an avenue for password changing whenever an admin password is provided using a microcontroller (ATMEGA 16). In achieving these objectives, the design was categorised into the software and the hardware section. Atmel Studio 5 and Proteus ISIS software were used for coding (C- Language) and simulation for the software section whereas; the hardware section comprises of a keypad, relay, buzzer and the microcontroller. The control unit either activate the pin in which the relay is connected to grant access to the user or activates the pin to which the buzzer is connected when the wrong password is used. The system is designed to activate the relay when the correct password is inserted; however, it activates the buzzer when the wrong pin is inserted depicting that it is an intruder. For flexibility, an admin password is provided which grants the owner access to an interface to change password whenever the need arises. The results presented show that the system responded as designed
