ATL Water Quality Sensor Lab Kit
ATL Water Quality Sensor Lab Kit — Measure TDS, Turbidity & Temperature with Arduino Nano
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Ever wondered if your drinking water is safe or how clean a pond really is? This kit turns that curiosity into a real electronic instrument. You’ll wire up three different water quality sensors on a breadboard, connect them to an Arduino Nano, and start reading TDS, turbidity, and temperature from actual water samples – just like a field scientist.
What You'll Build
You’ll assemble a compact monitoring station with a 16x2 LCD that shows live readings: total dissolved solids (ppm), turbidity (NTU), and temperature (°C). Dip the sensors into one of the five included sample cups and watch the numbers update instantly. By the end, you’ll have a portable water tester ready for your ATL lab exhibit or school science fair.
What You'll Learn
- Connect and calibrate a TDS sensor module to measure conductivity and estimate dissolved solids in water
- Use a turbidity sensor to detect suspended particles and understand how clarity relates to pollution
- Interface a waterproof DS18B20 temperature probe for precise thermal readings
- Display multi-sensor data on an I2C LCD, building a self-contained sensing system

Who This Kit Is For
Students in ATL Tinkering Labs, CBSE Class 6–10, and school eco-clubs will find this kit a direct bridge between NCERT environmental science topics and real electronics. It’s also a ready-to-use project for Smart India Hackathon Junior entries and science exhibitions where data-driven water quality demonstration scores high marks.
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 inside the box to launch the AI companion that walks you through every wiring and code step. You can also send photos or questions directly to our team on WhatsApp for quick help.
Can I test water from my home tap or a local pond?
Absolutely. The five sample cups are meant for precisely that – collect tap water, rainwater, pond water, or even RO-filtered water and compare their TDS, turbidity, and temperature readings side by side.
Do I need to solder anything?
No soldering required. All connections plug directly into the breadboard using the included M-M jumper wires. The I2C backpack snap-fits onto the LCD, keeping the build entirely plug-and-play.
Is it safe for middle-school students?
Yes. The entire circuit operates on 5V from the Arduino Nano via USB, so there’s no risk of shock. The TDS and turbidity sensors are fully enclosed, and the DS18B20 probe is rugged and waterproof.
Test water conductivity, turbidity and temperature in real water samples using simple sensor circuits. Science and electronics combined.
