Greenhouse Climate Monitor Kit v3
Greenhouse Climate Monitor Kit v3 — Build an Arduino Mega-Powered 18-Channel Spectral NDVI & Plant Stress Analyzer
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You're about to construct a professional-grade tool that reads 18 distinct wavelengths of light reflected from leaves. With the AS7265x spectral sensor array at its core, this kit computes NDVI, PRI, and custom stress indices right on the Arduino Mega — giving you early warning of nutrient deficiencies, water stress, or disease in your greenhouse crops before they become visible.
What You'll Build
A self-contained environmental station with a 2.4-inch color TFT that shows real-time temperature, humidity, atmospheric pressure, and live NDVI values. Every reading is time-stamped by the DS3231 RTC and saved to a microSD card. The AS7265x scans 18 channels from 410nm to 940nm, so you can map leaf reflectance, calculate vegetation indices, and log data for long-term trend analysis.
What You'll Learn
- Interface the AS7265x 18-channel spectral sensor with Arduino Mega using I²C and calibrate its gain settings
- Derive NDVI, Photochemical Reflectance Index (PRI), and custom stress ratios from raw reflectance values
- Fuse environmental data (DHT22, BMP280) with spectral readings and log them alongside RTC timestamps
- Solder components onto prototype PCB to create a rugged, deployable monitoring unit

Who This Kit Is For
Designed for India's agri-tech researchers, professional greenhouse managers, and BTech Agricultural Engineering or ECE students working on precision farming. Whether you're setting up a controlled experiment at an agricultural university, participating in the Smart India Hackathon with a crop stress theme, or deploying sensor networks in a commercial polyhouse, this kit delivers lab-grade spectral analysis you can build and iterate yourself.
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.
What if I get stuck during the build?
The AI companion provides pin-by-pin wiring checks and code walkthroughs. You can also send a WhatsApp message for direct troubleshooting from our team.
Can I use this sensor array outdoors in an open field?
The electronics are not weatherproof. For outdoor use, you’ll need an IP65 enclosure and protection for the sensor window. The kit is ideal for greenhouses and polyhouses where conditions are controlled.
Do I need prior soldering experience?
Basic soldering is required to assemble the prototype boards. The kit includes a soldering iron and wire, making it a complete bench project for those ready to build hardware hands-on.
How do I interpret NDVI values for my specific crop?
The AI companion explains the calculation and helps you establish baseline reflectance for healthy plants, then flags deviations that indicate stress — turning raw data into actionable insights for your greenhouse.
Greenhouse — AS7265x tri-spectral sensor array reads 18 wavelengths of reflected light from leaves to compute NDVI and stress indices.
