Hydroponics Nutrient Monitor Plus Kit with Arduino Mega + DHT22
Hydroponics Nutrient Monitor Plus Kit with Arduino Mega — Log, Analyse, and Predict Crop Yield
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your hydroponics setup into a smart agriculture experiment. Over 4 weeks, this kit logs temperature, humidity, soil moisture, and light levels to an SD card with precise timestamps. By the end, you'll have enough data to train a regression model that predicts crop yield — a core skill for modern precision farming.
What You'll Build
A fully assembled Arduino Mega–based sensor array that continuously monitors two grow zones, displaying live readings on an OLED screen and writing CSV logs to a microSD card every few minutes. Use the collected dataset — 4 weeks of hourly environmental snapshots — to build a multiple linear regression model and forecast the yield of your hydroponic crop.
What You'll Learn
- Calibrating and interfacing industrial-grade sensors (DHT22, soil moisture, BH1750) with an Arduino Mega
- Setting up a real-time clock (DS3231) to timestamp data logs for time-series analysis
- Writing sensor data to a microSD card in CSV format and designing a dashboard on the 0.96" OLED
- Applying regression algorithms (using Python or R) to the collected dataset to predict hydroponic yield

Who This Kit Is For
Ideal for B.Tech ECE, EEE, and Agricultural Engineering students working on Smart India Hackathon prototypes or capstone projects on precision farming. Also suitable for ATL Tinkering Lab mentors guiding advanced IoT experiments, and NIT, IIT, VIT, and BITS research groups needing a rugged, reproducible data acquisition unit.
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 to start a chat with your AI build companion, which knows every wire and resistor in this kit. If you need human help, our WhatsApp support line is answered by real builders in Bengaluru.
Do I need prior soldering experience?
The kit includes a soldering iron and solder, and the AI companion walks you through every joint on the PCB prototype board. A steady hand and patience are more important than past experience.
How do I perform the regression analysis for yield prediction?
Once you've collected your 4-week CSV log, the AI companion provides a step-by-step Python notebook that loads the data, cleans it, and fits a multiple linear regression model using scikit-learn — no prior ML knowledge required.
Can I monitor more than two grow zones?
You can chain additional DHT22 sensors on the Mega’s multiple digital pins; the companion will guide you through modifying the code to log extra channels. The kit’s 3 soil moisture probes are ready for three separate hydroponic troughs.
Hydroponics — Temperature, humidity, soil, light logged daily for 4 weeks. Regression model predicts yield.
