Hydroponics Nutrient Monitor Pro Kit with Arduino Mega + Sensor
Build a Multi-Node Hydroponics Monitoring Grid with the Arduino Mega Nutrient Monitor Pro 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.
You’ll construct a 4-node sensor grid that measures precise temperature gradients and moisture levels across a hydroponic setup. Each node reports back to a central Arduino Mega logger, which timestamps readings from a DS3231 RTC and writes them to SD — creating a spatial map of your growing environment that helps optimise nutrient delivery and light exposure.
What You'll Build
A field-ready monitoring system with four DS18B20 temperature probes and four capacitive soil moisture sensors arranged in a grid. The Arduino Mega manages all one-wire and analog input, while the 0.96-inch OLED cycles through node-by-node readings. All data streams to a CSV file on the microSD card, with timestamps for root-zone analysis. This kit prepares you for large-scale IoT deployments in controlled-environment agriculture.
What You'll Learn
- Interfacing multiple DS18B20 temperature sensors on a single one-wire bus using unique ROM addresses
- Reading capacitive moisture sensors and calibrating them for coco-peat, perlite, and nutrient film channels
- Logging structured data with RTC timestamps to an SD card for offline correlation and Excel/Google Sheets import
- Assembling and sealing a waterproof outdoor enclosure for long-term monitoring tests

Who This Kit Is For
B.Tech ECE/EEE/Agricultural Engineering final‑year students building IoT‑based precision farming projects, Smart India Hackathon teams tackling sustainable agriculture, researchers validating spatial moisture uniformity in hydroponic systems, and startup founders prototyping connected farm solutions. If you’re at IIT, NIT, VIT, BITS, or a state agricultural university, this kit saves weeks of parts hunting and debugging.
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 on the box for our AI build companion, trained on this exact project. You can also reach us on WhatsApp for human guidance within 24 hours.
Can this kit be used for soil farming as well?
Yes, the capacitive soil moisture sensors work reliably in soil, but the DS18B20 probes are designed for immersion in nutrient solutions or coco-peat — you may need to waterproof connections for outdoor soil use.
Does the kit include a power supply for long-term field deployment?
The kit includes a 9V battery snap for initial testing. For multi‑day logging, use an external 5V solar regulator or power bank; wiring hints are included in the companion guide.
Is prior Arduino experience required?
This is an advanced kit. You should be comfortable with Arduino IDE, basic soldering, and reading sensor datasheets. Our build companion will walk you through each step, but familiarity with multi‑sensor libraries helps.
