Crop Disease Early Warning Scanner Kit with Arduino Mega + Sensor
Build a Crop Disease Early Warning Scanner with Arduino Mega and AS7265x Spectral Sensor
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
By the time a farmer sees brown spots on a leaf, a fungal infection has already spread. This scanner captures spectral reflectance shifts — invisible to the human eye — that appear days before symptoms, logging the data with a timestamp and ambient light level onto an SD card. It’s a precision tool that puts lab-grade early warning into a handheld device you build and program yourself.
What You'll Build
A portable, battery-powered scanner that measures reflected light from leaves across 18 spectral channels from violet to near-infrared. The device computes a vegetation index, flags anomalies, and displays live readings on an OLED screen while storing every sample with a date-time stamp for trend analysis — exactly what a pathologist needs before visible decay sets in.
What You'll Learn
- Interpreting spectral reflectance signatures for plant stress
- Calibrating a multi-channel spectrometer (AS7265x) with ambient light correction
- Data logging with RTC synchronization and SD card storage
- Soldering and assembling a compact, field-ready prototype

Who This Kit Is For
B.Tech (ECE/EEE/Agri-engineering) students working on Smart India Hackathon challenges or final-year projects that demand real agricultural sensor fusion. Researchers prototyping precision plant health monitors, and advanced hobbyists who want a deployable, field-ready scanner to support farm advisory or rural agritech pilots in India.
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 to open the AI companion — it knows every pin, wiring step, and calibration detail for this kit. You can also share a photo on WhatsApp and a Compoden engineer will guide you directly.
How accurate is the spectral reflectance measurement compared to a lab spectrometer?
The AS7265x delivers 18-channel data in 10nm bins, proven for relative plant health indices like NDVI proxies. While not a substitute for a lab-grade device, it reliably detects stress trends when you perform a white-reference calibration before each sampling session.
Does this kit require internet for logging?
No. All data logs to the microSD card with an RTC timestamp. The OLED shows live reflectance values, so you can use the scanner in remote fields with zero connectivity.
Can I modify it to send SMS alerts when an anomaly is detected?
Yes. The Arduino Mega has spare UARTs for a GSM module. The AI companion can suggest the exact wiring and code changes to add an SMS alert when the vegetation index crosses a threshold you define.
AS7265x spectral sensor detects reflectance anomaly in leaves that precedes visible disease symptoms.
