ESP32-CAM Drone GPS Kit: Capture Multispectral NDVI Maps
ESP32-CAM Multispectral Drone GPS Kit: Capture NDVI Maps 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.
You'll build a self-contained ESP32-CAM imaging system that mounts on a standard drone frame, captures both visible and near-infrared photos with precise GPS coordinates, and calculates Normalized Difference Vegetation Index (NDVI) - the industry standard for crop health analysis. This kit equips you to monitor plant stress, irrigation efficiency, and fertilizer response across your fields, turning raw aerial data into actionable farming insights using open-source components and proven hardware.
What You'll Build
You'll construct a modular drone payload that integrates a multispectral camera, GPS module, real-time clock, and power management onto custom PCBs. The system captures synchronized image pairs - one from the BH1750 ambient light sensor for visible reference, one from the AS7265x 18-channel spectral sensor spanning visible to near-infrared. All data is stamped with precise GPS coordinates from the NEO-6M module and saved to a microSD card for post-flight NDVI calculation, giving you a portable, repeatable crop health mapping tool.
What You'll Learn
- Designing a power-efficient payload using an LM2596 buck converter and LiPo battery management with TP4056 charging module.
- Interfacing multiple I2C and UART sensors - AS7265x, BH1750, NEO-6M GPS, DS3231 RTC - on a single ESP32-CAM board.
- Writing firmware to trigger synchronized multispectral capture, store geotagged images, and compute NDVI from raw sensor data.
- Integrating drone flight dynamics with payload data logging for precision agriculture mapping missions.

Who This Kit Is For
This advanced kit is designed for agriculture professionals, agritech researchers, and drone enthusiasts in India who need ground-truth crop data without the high cost of commercial multispectral cameras. It fits perfectly into B.Tech ECE/EEE students working on precision farming projects, participants in Smart India Hackathon challenges around agricultural monitoring, and startups building low-cost NDVI mapping services. If you have prior experience with ESP32 programming and basic soldering, you'll find this project deeply rewarding and a tangible addition to your agritech portfolio.
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?
Our AI companion - accessed instantly via QR code - walks you through each step, and if you need human help, our WhatsApp support team responds within 12 hours.
Can I use this payload on any drone frame?
The included drone frame is a lightweight mount compatible with most 250-450 size quadcopters that have a payload rail. You can also adapt the PCB and components to your own frame with basic mechanical skills.
How accurate is the NDVI calculation?
With proper calibration using the near-infrared channels of the AS7265x and visible light from the BH1750, the index accuracy rivals entry-level commercial systems. We provide step-by-step calibration guidance in the build manual.
Is soldering experience required?
Yes, you'll need to solder the modules onto the prototype PCBs. The kit includes a soldering iron and solder wire. If you are new to soldering, the AI companion includes a basic soldering tutorial to get you started.
