Security, defined as protection against external threats, is a critical concern for homes and offices. Intrusion, characterized by unauthorized access, presents a significant challenge to maintaining security. This research aims to address this issue by designing and implementing an automated intrusion detection system utilizing a combination of sensors and communication technologies. The research introduced an automated intrusion detection system for homes and offices, combining sensors such as a PIR sensor for detecting unauthorized motion, magnetic switches for unauthorized entry detection, and a GSM module for notifying property owners. Employing the ATmega328P microcontroller, sensor data is analysed to generate early intrusion alerts, prompting phone call notifications via the GSM module. Practical implementation involved breadboarding, soldering, and rigorous testing, ensuring proper functionality under real-world conditions. The implemented intrusion detection system effectively utilizes magnetic switches and a Passive Infrared (PIR) sensor to detect unauthorized entry and motion within the premises, respectively. Upon detection, the system promptly analyses the situation and alerts the property owner via phone call, enabling swift response measures. This real-time notification system enhances proactive security management, minimizing the risk of further intrusion and ensuring the safety of the property. The multi-sensor intrusion detection system, incorporating PIR sensors, magnetic switches, and a GSM-based phone call gateway, effectively alerts property owners of unauthorized intrusions in real-time. Demonstrating its efficacy through rigorous testing, the system offers enhanced security for both residential and commercial environments.
