Design and Implementation of an Intelligent Microcontroller-Based Home Security System

This research presents design and implementation of an intelligent microcontroller- based home security system aimed at enhancing residential safety through real-time, multi- layered protection and user-friendly management. Leveragig PIC 16F877A microcontroller and an HC06 Bluetooth module, this system enables wireless communication with a dedicated Android application for remote monitoring, arming, disarming and emergency notifications. The system integrates infrared motion sensors, magnetic contacts, and automated response protocols to detect unauthorised entry, activating a series of responses including alarms, image capture and SMS alerts. Unlike traditional systems which are often limited to basic alarm triggers, this design captures images of intruders, stores evidence and sends images directly to the home owner’s smartphone. The system was developed with MickroC software and MIT Application Inventor, this system combines hardware versatility with software flexibility, creating a scalable, cost-effective solution suitable for modern home security needs.
