The rapid growth in energy demand and the increasing need for accurate monitoring have made traditional energy meters inadequate for modern applications. This project presents the design and implementation of an IoT-Based Smart Energy Meter capable of measuring, displaying, and transmitting real-time electrical data over the internet. The system uses an Arduino Uno as the main controller, integrated with a PZEM-004T power sensor to measure voltage, current, and power consumption. The readings are displayed locally on a 16×2 LCD screen and simultaneously transmitted to the ThingSpeak IoT platform through an ESP-01S Wi-Fi module, allowing remote monitoring through mobile or web interfaces.
The device also includes an automatic overload protection mechanism, which disconnects the load using a relay and triggers an alarm whenever the current exceeds a set threshold. Supporting components such as transistors (BC548), a 7805 voltage regulator, LED indicators, and a buzzer ensure system stability and safety. The entire circuit is powered by a 12V DC adapter, regulated to 5V for the control units. Testing results show that the system provides accurate readings with less than 3% deviation compared to a standard energy meter. It successfully transmits data to the cloud and reacts promptly to overload conditions. This project demonstrates a low-cost, reliable, and efficient solution for smart home energy management and offers a foundation for future improvements such as mobile app integration and multi-load monitoring

This project involves the design of a hybrid renewable energy system using solar and wind for residential areas and to use the system to generate sustainable electricity for household consumption, independent of fluctuations in the weather. A review of previous works was carried out, radiation (solar) and wind data (speed) was collected using Northern part of Nigeria as a case study and then load listing for a typical household was done. The subsystem of the Hybrid Renewable system was organized in a block diagram and then each of the subsystem was designed. The Design Calculation (result and finding) was that a typical household requiring 11KW per day. Each Subsystem requires a PV subsystem requires with 6 solar panels of 1000w connected in series, Wind subsystem with rotor blade Radius/Length of 5m is required with 11kw 24V Turbine, an Energy storage subsystem of 24V, 13000AH which is 10 (1300AH) batteries in series and an Inverter required is 15KW 24V inverter.
Overall, this research provides a comprehensive framework for the design of a hybrid renewable energy system that combines the strengths of solar and wind resources. The proposed system offers a reliable and environmentally friendly solution to meet the increasing energy demands while reducing greenhouse gas emissions, ultimately contributing to a cleaner and more sustainable energy in the future.
