Solar Panel Tracker Kit with ESP32 + LDR: Stream Live Light Data to a Browser Graph

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Turn an ESP32 into a live data broadcaster that mimics a solar panel tracker. With an LDR to detect light and potentiometers to adjust the virtual tracking angle, you’ll code a system that streams sensor values to a browser over WiFi. The dashboard plots a real-time graph, showing exactly how the tracker “sees” the sun and responds. This is the perfect first step into IoT, ADC, and WebSocket communication—no prior web development experience needed.

What You'll Build

Assemble a sensor circuit on a breadboard, then program the ESP32 to read light intensity and angle inputs. You’ll create a built-in web page that updates a live graph as you move the LDR and twist the potentiometer, simulating how a solar tracker follows the sun. Share the dashboard on any phone or laptop connected to the same WiFi.

What You'll Learn

• How to read analog sensors—LDR and potentiometer—with the ESP32’s ADC
• Setting up an ESP32 as a WiFi station to host a web interface
• Pushing live data to a browser using WebSockets without page refresh
• Plotting a real‑time graph with basic HTML and JavaScript

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students tackling IoT in their curriculum, B.Tech ECE/EEE first‑year mini projects, and ATL Tinkering Lab coordinators will find this kit a ready‑to‑use module. Smart India Hackathon participants can prototype sensor‑to‑dashboard workflows quickly. The simple wiring and guided code also make it a hit for parent‑child weekend builds at home.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
