Field Crop Stress Monitor Kit with Arduino Mega + Sensor
Build a Field Crop Stress Monitor with Arduino Mega – 4-Node Sensor Grid Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Unlock precision agriculture by building a four-node sensor grid that monitors soil moisture and temperature across your crop field. This kit lets you collect, log, and analyze spatial stress data to make informed irrigation decisions — all with an Arduino Mega brain and onboard OLED display. You’ll deploy four DS18B20 probes and soil moisture sensors, wire them for robust field use, and walk away with real-time dashboards and CSV logs.
What You'll Build
A rugged field-deployable monitoring system that records soil moisture and temperature from four strategic points, with timestamped data saved to an SD card. You’ll see live readings on the OLED and create a CSV dataset ready for analysis in Excel or Python, allowing you to map drought stress and plan precise watering.
What You'll Learn
- Multiplex four DS18B20 temperature sensors using OneWire protocol
- Calibrate soil moisture sensors for your specific soil type
- Log timestamped data to an SD card with SPI and DS3231 RTC
- Analyze spatial patterns to detect early crop water stress

Who This Kit Is For
This kit is built for final-year B.Tech ECE/EEE students working on precision agriculture capstone projects, Smart India Hackathon teams prototyping IoT for farms, and advanced hobbyists exploring spatial data logging. If you're at IIT, NIT, VIT, or BITS Pilani and need a field-ready prototype that outputs analytics-ready data, this is your solution.
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 guides you step-by-step, and you can send a WhatsApp message to our support team for tailored help.
How do I interpret the data to detect crop stress?
The logged CSV shows soil moisture and temperature per node; a sudden moisture drop at one node signals local drought stress, while high temperature corroborates heat stress. The companion explains threshold setting for your crop type.
Can this system be powered by solar for continuous monitoring?
Yes, the kit includes a 9V battery snap for testing, but you can attach a solar panel and LiPo battery to the input for round‑the‑clock field deployment. The enclosure protects the circuit.
Are there extra GPIOs to add a rainfall sensor?
Absolutely, the Arduino Mega has ample analog and digital pins. You can wire a tipping‑bucket rain gauge to log precipitation alongside soil data with minimal code changes.
Four-node DS18B20 + soil moisture array deployed in field grid. Central logger correlates spatial data on SD.
