ESP32 Smart Solar Tracking System with Mobile App

ESP32 IoT Smart Solar Sun Tracking System with Mobile App

The ESP32 IoT Smart Solar Sun Tracking System is an advanced, practical, and educational project designed for students, science fairs, and university final year submissions. This project demonstrates how solar energy efficiency can be improved by automatically tracking the sun’s direction using light sensors and real-time control logic. Powered by an ESP32 WiFi and Bluetooth development board, the system provides live monitoring of generated solar voltage and temperature through both a mobile application and an LCD display. An intelligent cooling mechanism activates a water pump when temperature exceeds a defined limit, ensuring system stability and improved performance.

This project is ideal for learners who want to explore IoT, renewable energy, embedded systems, and mobile app integration in a single working model. It is widely used by students purchasing project kits from Bigyan Project for academic learning, demonstrations, and final year evaluations.
