The main objective of this project is to design and develop a solar energy measurement system for monitoring important solar panel parameters such as voltage, current, temperature, and light intensity using multiple sensors. The light intensity is measured using an LDR sensor, while an ACS712 current sensor is used to measure the current generated by the solar panel. A temperature sensor is used to monitor the panel temperature. The solar panel voltage is measured by connecting the panel output to the Arduino UNO through a potential divider circuit. The Arduino UNO microcontroller acts as the main controlling unit of the system. The measured parameters are collected and processed by the Arduino and transmitted to the ThingSpeak IoT platform through a Wi-Fi module. The voltage, current, temperature, and light intensity values are continuously monitored and updated on the ThingSpeak webpage along with the corresponding date and time. The microcontroller is programmed using Embedded C language to perform the required monitoring and communication tasks. ThingSpeak is an open-source IoT platform that allows data to be stored, monitored, and retrieved through the Internet using communication protocols such as HTTP. The proposed system continuously monitors the solar panel parameters and uploads the measured data to the IoT platform for real-time observation. By using this technology, the performance and efficiency of solar energy systems can be monitored effectively, helping users analyze the operating conditions of solar panels and improve their overall utilization.
