DESIGN AND IMPLEMENTATION OF MICROCONTROLLER INTRUDER BURGLAR ALARM SYSTEM

Abstract

This project work presents the design and Implementation of an intelligent intruder burglar alarm system. This system is a security system to be deployed in areas where intrusion is not expected. This system has six major parts listed as follows; the power supply unit, the control system, the motion sensor, the LCD display, the activation buttons and the security alarm system. The power supply unit is made up of; the a.c power source. The motion sensor used in this work is the PIR sensor.The LCD used is the 4 by 16-character LCD and displays the presence of intrusion if any intrusion is detected. The alarm system is a low-cost alarm module which is triggered by the control system through a transistor switch arrangement in the event of any intrusion. An activation and deactivation buttons allow users to activate or deactivate the system as need arises. The microcontroller ATEMEGA328P controls the automatic and intelligent operation of the entire system. The resulting security system is a low cost but very efficient intelligen
