ESP32 TinyML On-Device Water Quality Monitor

Membranes & Advanced FiltrationEst. CapEx: Low-cost / Locally fabricated


Technical Overview

A low-cost, real-time water quality monitoring system built around the ESP32 microcontroller that measures pH, TDS, temperature, and turbidity. It integrates an on-device neural network (TinyML via TensorFlow Lite for Microcontrollers) to classify water impurity events locally without requiring constant cloud connectivity, making it ideal for decentralized and remote deployments.


Key Specifications & Engineering Parameters

Parameter Specification
Category Membranes & Advanced Filtration
Capital Cost Low-cost / Locally fabricated
Primary Mechanism Analog and digital sensors feed parameter data into an ESP32 microcontroller, where a trained neural network processes the readings in real time to categorize water as ‘Normal’, ‘Rainwater Runoff’, or ‘Chemical’ with 99.28% accuracy. An intelligent fluctuation-based logging algorithm drastically reduces storage writes, and an automated pump control actuator enables autonomous response when anomalies are detected.
Target Scale Household / Village Cluster
Standard Lifespan 10 - 20 Years
