SOLAR BASED HOME AUTOMATION SYSTEM

Abstract: The Solar Energy-Based Home Automation System Using Mobile Bluetooth integrates renewable energy with advanced smart home technologies to enhance comfort, security, and energy efficiency. This system leverages solar energy as its primary power source and utilizes a Bluetooth-enabled mobile application for monitoring and controlling household appliances. It automates various functions, including lighting, ventilation, and home security, thereby reducing energy wastage and enhancing convenience. A significant feature of this system is the LPG detection capability, which triggers the automatic opening of windows using a servo motor and sends alerts to the user’s mobile device via Bluetooth for immediate response. The integration of an Arduino Uno microcontroller, HC-05 Bluetooth module, LCD display, LPG sensor, relay modules, and solar panels ensures reliable performance and cost-effectiveness.
