The increasing demand for electrical energy and the growing emphasis on sustainable power utilization have accelerated the development of intelligent home energy management systems. This paper presents the design and implementation of a Smart Home Energy Management System (SHEMS) that integrates renewable energy sources with ZigBee-based wireless communication and an Arduino (ATmega328) controller. The proposed system is structured into two major sections: a transmitter unit and a receiver unit. The transmitter unit consists of a solar panel, charging control circuit, 12 V battery, voltage and current sensors, relay-based load control, and an ATmega328 microcontroller. It continuously monitors energy generation, battery status, and load consumption, while transmitting real-time data through a ZigBee module. The receiver unit receives sensor data via ZigBee, processes it using an ATmega328 controller, and forwards the information to a NodeMCU module for IoT-based cloud communication, enabling remote monitoring through mobile or laptop interfaces. The system supports efficient energy utilization by prioritizing renewable energy usage, enabling intelligent load control, and providing real-time energy insights to users. Experimental results demonstrate reliable communication, accurate energy monitoring, and effective load management. The proposed architecture offers a low-cost, scalable, and energy-efficient solution suitable for smart homes and small-scale residential applications.
