        abstract = {This project presents an IoT-based renewable energy monitoring kit designed to measure, display, and transmit real-time electrical parameters from a small-scale solar power system. The system uses a solar panel as the primary energy source, whose output voltage and current are sensed using a voltage divider-based voltage sensor and a Hall-effect or shunt-based current sensor. The raw solar output is passed through a rectifier, filter capacitor, and a 7805-voltage regulator to obtain a stable 5 V DC supply for the microcontroller and electronic circuitry. A NodeMCU ESP8266 microcontroller is used as the core processing and communication unit. It continuously acquires analog input values through its ADC pin, calculates real-time voltage and current, and displays them on a 16×2 LCD module. Six LEDs with resistors are included as load indicators to represent different loading conditions from the solar panel, allowing visible demonstration of how voltage and current vary with changing load. In addition, the ESP8266 is programmed to connect to Wi-Fi and upload the measured parameters to the cloud through ThingSpeak, enabling online monitoring, data logging, and graphical visualization. This cloud- based IoT integration makes the system suitable for remote supervision and educational demonstrations. The proposed design is low-cost, compact, and uses easily available components, making it suitable for labs and small rural setups where conventional monitoring instruments are unavailable. Overall, this project demonstrates how solar energy generation can be effectively monitored using embedded systems and IoT, contributing toward smarter renewable energy management.},
