ESP32 Smart Solar Tracking System with Mobile App

ESP32 IoT Smart Solar Tracking Project with Mobile App This ESP32-based smart solar sun tracker project is designed for students and university final year submissions. The system automatically tracks sunlight using LDR sensors, rotates the solar panel with a servo motor, and displays live voltage and temperature data on both a mobile app and LCD display. An automatic cooling water pump activates when temperature rises, making the project practical and innovative.
