Water Quality Kit: Measure TDS, Turbidity, Temp with Arduino Uno
Build a Drinking Water Safety Classifier with Arduino Uno & Multi-Sensor Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine lighting up an OLED with a clear verdict on the water you drink every day - safe, marginal, or unsafe - by combining three real-world sensor readings in one Arduino-powered station. This kit puts a complete water quality monitor in your hands, turning a lab-grade concept into a compact, working prototype that analyses TDS, turbidity, and temperature in minutes.
What You'll Build
You'll assemble a bench-top unit that pulls live readings from a TDS EC probe, a turbidity sensor, and a waterproof DS18B20 temperature sensor. The Arduino Uno seamlessly merges those values through a weighted scoring algorithm, instantly classifying the water's safety and displaying the result on a crisp 0.96-inch OLED. The final instrument is a practical screening tool - perfect for field trips, school exhibitions, or evaluating your home water filter's performance.
What You'll Learn
- Interface both analogue (TDS, turbidity) and digital (DS18B20) sensors with Arduino Uno, including the OneWire communication protocol
- Convert electrical conductivity into parts per million (ppm) and calibrate the TDS probe for repeatable readings
- Interpret turbidity sensor voltage as NTU, accounting for ambient light and sample consistency
- Design and tune a multi-parameter classification algorithm that outputs a user-friendly water safety score

Who This Kit Is For
This kit is a natural fit for CBSE Class 11-12 students tackling physics or environmental investigatory projects. B.Tech ECE/EEE undergraduates will appreciate the clean integration of analogue signal conditioning and digital logic, while Smart India Hackathon participants can use it to prototype a rapid water-screening solution. ATL Tinkering Labs and engineering aspirants from IIT, NIT, VIT, or BITS Pilani will find it an inspiring, real-world sensing build that links classroom theory to immediate, visible results.
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?
The kit includes a QR code to an AI companion pre-loaded with the project steps, and our team is available on WhatsApp to help you troubleshoot sensor wiring or code.
How accurate are the TDS and turbidity readings?
The TDS meter delivers �10% accuracy after calibration, suitable for field screening. The turbidity sensor gives comparative clarity measurements - not lab-grade but reliable for classifying water as safe, marginal, or unsafe.
Can I change the safety thresholds?
Absolutely. The Arduino sketch is open-source and clearly commented, so you can easily adjust the ppm and NTU cut-offs to match Indian drinking water standards (IS 10500) or your local conditions.
Is the Arduino Uno board genuine?
Yes, a genuine Arduino Uno R3 is included, along with all the sensors and components needed for a working multi-parameter water quality monitor.
TDS + turbidity + temperature combined. Score all three on OLED and classify water as safe, marginal or unsafe.
