ESP32 Smart Aquaponics Nutrient Prediction Kit - Water Quality Logging India
ESP32 Smart Aquaponics Nutrient Prediction Kit - Turn Water Data into Feeding Forecasts
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Aquaponics and fish farming demand precise water chemistry. Fluctuations in TDS, pH, dissolved oxygen, and temperature directly affect fish health and plant growth. This kit turns your ESP32 into a multi-parameter logger that captures those readings every few minutes, stores them on a microSD card, and feeds them into a regression model - so you can predict the next day's nutrient requirements before trouble appears.
What You'll Build
You'll assemble a rugged, waterproof-station that continuously monitors two water temperature points, electrical conductivity (TDS), pH, and dissolved oxygen. An RTC module timestamps every sample, while the OLED shows real-time values. After logging a week of data alongside your manual feeding records, you'll train a simple regression model to forecast how much feed to add, balancing ammonia levels and plant uptake.
What You'll Learn
- Calibrate electrochemical sensors (pH, DO, TDS) and apply temperature compensation
- Implement interrupt-driven logging on ESP32 with DS3231 RTC for time-stamped CSV files
- Design a portable 12V power supply with buck converter and noise filtering for analog readings
- Build and evaluate a multiple linear regression model linking water parameters to feeding quantity

Who This Kit Is For
Aquaponics practitioners, agriculture engineering students (MTech/BTech), and researchers working on precision farming. It fits perfectly into Smart India Hackathon challenges around sustainable food production, IIT/NIT/VIT/BITS IoT projects, and agritech startups validating sensor-based feeding algorithms. If you're a serious hobbyist managing a backyard fish-and-vegetable system and want to move beyond guesswork, this kit gives you the hardware and model-building framework.
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?
Open the AI companion from the QR code on your box - it knows every component and step. For tricky calibration or soldering, we'll respond on WhatsApp within hours.
Can this kit monitor multiple fish tanks?
Yes. The DS18B20 sensors can be daisy-chained, and the microSD logging structure supports multi-tank CSV files. You just need additional waterproof probes and enclosure extensions.
Do I need prior machine learning experience to build the regression model?
No. Our guide walks you through extracting the CSV data and applying a simple linear regression using open-source tools - no ML background required.
How do I waterproof the electronics after assembly?
The kit includes a waterproof enclosure with cable glands for sensor leads. Combined with conformal coating (instructions included), it withstands high-humidity greenhouse environments.
Cooking - TDS EC, pH, DO, temp and fish feeding logged to build regression model predicting daily nutrient needs.
