Hyperspectral Plant Stress Monitor
Build a Hyperspectral Plant Stress Monitor with Arduino – 18 Wavelengths for Precision Agriculture
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform how you assess plant vitality with a custom spectral sensor array that captures 18 discrete light wavelengths reflected from leaves. Using the AS7265x tri-spectral chipset, this kit enables calibrated reflectance measurements to compute NDVI, PRI, and custom stress indices — essential for research, phenotyping, or field-scale crop monitoring. Whether you're validating precision agriculture algorithms or running a controlled-environment study, the monitor gives you lab-grade spectral data in a portable, Arduino-driven design.
What You'll Build
A fully integrated handheld (or tripod-mountable) device powered by an Arduino Mega 2560. It reads leaf reflectance across 18 visible and near-infrared channels, simultaneously logs air temperature, humidity, and atmospheric pressure, time-stamps every reading with a DS3231 RTC, displays real-time NDVI and stress trends on a 2.4-inch TFT screen, and stores all data on a microSD card. You get a self-contained tool for rapid, repeatable plant health surveys.
What You'll Learn
- Measure leaf reflectance across 18 spectral bands using the AS7265x sensor and interpret raw values.
- Calculate Normalized Difference Vegetation Index (NDVI) and other vegetation indices from multiband data.
- Integrate environmental sensors (temperature, humidity, atmospheric pressure) to contextualize plant stress conditions.
- Engineer a reliable field instrument — soldering, PCB prototyping, power management, and data logging to microSD.

Who This Kit Is For
Advanced students and professionals building precision agriculture instrumentation. It fits B.Tech/MTech ECE, Agri-Engineering, and Environmental Science final-year projects, ICAR researcher field trials, Smart India Hackathon teams tackling crop health monitoring, and Tinkering Lab mentors setting up spectral phenotyping demonstrations. If you need a deployable sensor node rather than a toy, this kit delivers the spectral depth and data logging you require.
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?
Scan the QR code inside the box to access our AI companion, which has step-by-step troubleshooting for every assembly stage. If you need human help, WhatsApp us — our team responds within hours.
Can this kit detect specific nutrient deficiencies?
It measures reflectance across bands linked to chlorophyll, carotenoids, and water absorption. While it doesn't diagnose nutrients directly, you can compute indices like NDVI, PRI, and WBI that correlate with nitrogen and water stress; calibration against tissue tests is needed for quantitative estimates.
Is soldering required?
Yes, this is an advanced kit that includes a soldering iron and solder wire. You'll mount the prototype boards, sensors, and wiring, gaining real-world fabrication skills in the process.
How do I analyze the logged data?
The microSD stores CSV files with timestamped reflectance, NDVI, and environmental readings. Open them in Excel, Python, or MATLAB for trend analysis, spectral signature comparisons, or integration into GIS workflows.
