Plant Light Monitor Pro Kit: Arduino Solar Tracker for Healthier Indoor Gardens

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

Indoor plants often struggle to get enough light, especially in apartments or during cloudy seasons. This kit lets you build a smart two-axis light tracker that continuously orients a small solar panel (or grow light) toward the brightest source, using four LDR sensors, two servo motors, and an Arduino Uno. It’s a practical lesson in solar tracking — the same principle used in spacecraft and solar farms — applied to your own windowsill garden.

What You'll Build

A compact, self-correcting tracking system that reads light intensity from four directions (N, S, E, W), compares them, and smoothly moves the panel to the brightest spot. The 0.96-inch OLED displays real-time light levels and servo positions, so you can see exactly how your build responds to changing sunlight through the day.

What You'll Learn

• How LDR sensors work and how to read differential light intensity with Arduino
• Servo motor control and multi-axis mechanical design
• Real-time data display on OLED screen using I²C protocol
• Programming logic for comparing sensor values and making decisions with conditional loops and mapping

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for CBSE Class 11–12 students exploring sensor-based physics projects, B.Tech ECE/EEE first-years building a working solar tracker as a mini project, and Smart India Hackathon teams prototyping light-following systems. ATL tinkering labs and hobbyists from IIT/NIT/VIT/BITS will find it a solid, ready-to-use base for advanced experimentation with automated plant care.

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.
