Abstract

This project addresses the challenge of creating sustainable and efficient home security system that reduces the reliance on conventional energy sources. It explores the development of a smart home security device powered by photovoltaic solar energy, integrating Internet of Things (IoT) technology, advanced security features, and smart home functionalities to enhance convenience, safety, and sustainability. The system comprises real-time motion detection, live video streaming via ESP32-CAM, gas leak detection with MQ2 sensors, and temperature and humidity monitoring through DHT11 sensors, all managed remotely via the Blynk app. After the completion of software simulation and hardware testing, the device demonstrated reliable performance with an average solar panel power output of 3.897 W and a peak charging efficiency supporting a 12V SLA battery. The MQ2 sensor achieved 95% accuracy in detecting gas leaks, while the PIR sensor and ESP32-CAM provided real-time alerts and video streaming to effectively monitor motion. Temperature and humidity Readings varied predictably, enhancing environmental awareness. Remote control of LED Lighting demonstrated enhanced user convenience and security. The project successfully reduced energy reliance on conventional grids by 40% and lowered carbon emissions by 30%, exemplifying a scalable, cost-effective solution for sustainable and secure residential living.
