Abstract

Efficient energy consumption is a critical challenge in modern households, as significant power is wasted due to human negligence. This paper presents a solar-powered home automation system designed to optimize energy usage by automating fan and light control. The system employs an IR sensor to detect human presence, enabling automatic ON/OFF functionality for fans and lights. Additionally, an LDR sensor manages lighting based on ambient brightness, while a PTC temperature sensor regulates fan operation according to room temperature. By integrating relays, sensors, and a digital temperature controller, the system operates seamlessly without human intervention, enhancing flexibility and reliability. This automation is particularly beneficial for elderly and disabled individuals, offering them improved convenience and accessibility. The proposed solution significantly reduces electricity wastage, promotes sustainable energy use through solar power integration, and enhances user comfort in smart home environments.
