GSM-Based Home Security System Using Arduino Microcontroller

In response to the escalating demand for cutting-edge security systems due to the surge in criminal activities in the 21st century, to formulate a comprehensive home security solution is the main work of this project. Our system integrates an Arduino Uno microcontroller, a SIM800L GSM module for mobile communication, and a combination of security sensors including a LDR sensor, laser for intrusion detection, MQ-2 sensor for gas leakage identification, and a smoke detector for fire hazard awareness. This integration facilitates real- time alerts and notifications to homeowners in case of potential threats, including unauthorized intrusion, fire hazards, and gas leaks. Leveraging advanced technology at an affordable cost, our Integrated Home Security framework efficiently detects and responds to human movement, assuring enhanced security for residential communities. Through the exploration and implementation of these key components, this research contributes to the advancement and enhancement of home security systems, ensuring the safety and well-being of residential communities.
