Hydroponics Nutrient Monitor Kit
Hydroponics Nutrient Monitor Kit — Build a Climate Dataset Logger with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Hydroponic growers and agricultural researchers know that plant yield depends on microclimate consistency. This kit equips you to move beyond guesswork — log dual-point temperature, humidity, ambient light, and soil moisture every day to a microSD card, building a timestamped dataset you can correlate with plant growth cycles. Whether you are prototyping for a Smart India Hackathon agri-tech solution or developing a B.Tech final-year project, the monitor delivers lab-grade logging without juggling multiple breakout boards.
What You'll Build
You will assemble a self-contained environmental logger using an Arduino Mega 2560. Two DHT22 sensors capture temperature and humidity at canopy and root zones; a BH1750 measures photosynthetically active light; two resistive soil moisture probes track substrate water content. A DS3231 RTC stamps every reading, and a 0.96-inch OLED gives instant spot checks. Data writes automatically to a CSV on microSD — ready for Excel, Python, or MATLAB correlation analysis.
What You'll Learn
- Multiplexing multiple I2C sensors on a single bus without address conflicts
- Logging timestamped environmental data to a FAT32-formatted SD card
- Calibrating resistive soil moisture sensors for repeatable readings
- Designing a low-power field-deployable monitoring circuit with battery backup

Who This Kit Is For
This advanced kit fits B.Tech ECE/EEE students working on agricultural IoT capstone projects, CBSE Class 12 students exploring hydroponics in ATL Tinkering Labs, and teams preparing for Smart India Hackathon challenges involving precision farming. Research enthusiasts at IITs, NITs, and VIT will find the ready-to-log hardware accelerates data collection for paper-worthy correlation studies.
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 to start a conversation with our AI companion, custom-trained on this kit's wiring and code. For deeper issues, WhatsApp our support engineers — we reply within hours.
Can I log more than two soil moisture zones?
Yes, the Mega 2560 handles many analog inputs. The kit includes two probes, but you can easily extend using the extra 10kΩ resistors and PCB boards to add up to six more zones.
How do I correlate plant growth with the data?
The CSV file includes RTC timestamps; overlay the data on a timeline with your plant height or leaf count measurements. The AI companion provides a Python script to generate plots from the SD card directly.
Is the kit ready for outdoor field use?
The sensors and RTC run reliably in non-condensing humidity. For permanent outdoor deployment, add a simple rain enclosure — the battery snap and compact PCB layout make it easy to fit inside a weatherproof box.
Hydroponics — Logs temperature, humidity, light and soil moisture daily to SD to build a plant growth climate correlation dataset.
