ESP32 Pool Water Quality Kit
ESP32 Smart Pool Monitor Kit – Predict Water Quality Index with TFLite
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Most pool owners rely on test strips or expensive lab visits to check water quality — but neither gives a real-time picture of what’s actually happening in the water. This kit lets you build a multi-sensor system that continuously measures pH, TDS/EC, dissolved oxygen, and turbidity, then feeds that data to a TensorFlow Lite regression model running directly on the ESP32-S3. The model predicts a comprehensive Water Quality Index (WQI) and flags likely contaminant types, allowing you to treat problems before swimmers even notice.
What You'll Build
You’ll assemble a solar-powered, waterproof monitoring node that reads all four critical pool parameters every few minutes. The ESP32 relays predictions via LoRa to a dashboard or your phone, while an onboard RTC timestamps each record to an SD card. After the build, you’ll have a self-contained edge AI system that tells you not just “pH is low” but whether the pattern suggests organic contamination, mineral scaling, or chlorine imbalance — without any cloud dependency.
What You'll Learn
- Calibrating analog pH, DO, and TDS modules to laboratory-grade accuracy for long-term stability
- Implementing sensor fusion and preprocessing pipelines in MicroPython or Arduino before feeding a TFLite model
- Training and quantizing a regression model to predict WQI and contamination categories on resource-constrained hardware
- Designing a solar-powered LoRa telemetry node with deep-sleep power management and local SD card logging

Who This Kit Is For
This advanced kit is built for final-year B.Tech ECE/EEE students developing IoT-based environmental projects, Smart India Hackathon teams tackling water sustainability challenges, and pool maintenance businesses looking for a data-driven monitoring prototype. It’s equally suited for researchers at IITs, NITs, or VIT working on edge AI for water quality, and for experienced hobbyists who want to go beyond simple sensor readouts to a truly intelligent embedded system.
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 launch the AI companion, which walks you through every wiring diagram, calibration step, and TFLite deployment. For trickier issues, WhatsApp with our support team directly from the companion interface.
Can this kit detect specific pool chemicals like chlorine or algaecide?
The sensor array doesn’t measure individual chemicals, but the TFLite model infers contaminant categories from the combined pattern of pH, TDS, DO, and turbidity. It can flag organic load (suggesting algae), mineral scaling, or insufficient sanitization based on deviations from typical pool water profiles.
Is the system durable enough for permanent outdoor installation?
Yes. The included waterproof enclosure, solar-charged 18650 batteries, and buck converter are designed for continuous exposure. The LoRa link transmits small data payloads over several hundred meters, so the node can sit by the pool edge year-round.
Do I need prior machine learning experience to use the TFLite model?
The kit includes a pre-trained and quantized model ready to flash onto the ESP32. You’ll learn how to tune it during the build, but no ML training is required to get the system predicting WQI out of the box.
Pool Maintenance — TDS EC + pH + DO + turbidity sensor array feeds TFLite regression model that predicts WQI and contaminant type.
