Water Quality Lab Kit

This kit serves one of our pillars: Water — technology in the service of nature.

Turn any glass of water into data. This lab measures how pure your water is (dissolved solids), its temperature, and how cloudy it is — and shows the results on a screen. Test tap water, the Nile, a filter, or rainwater, and discover what is really in what we drink.

What's inside the kit?

• ESP-32S 30Pin Dev Board WiFi Bluetooth CP2102 — WiFi brain that reads the sensors
• TDS Meter Analog Sensor V1.0 — Measures water purity (dissolved solids / TDS)
• DS18B20 Digital Temperature Sensor — Waterproof temperature probe
• 0.96" OLED LCD Module — Shows live readings on screen
• BB-01 Breadboard 830 Tie Point — Build base (full breadboard)
• BB-J140 Connecting Jumper Wires for Breadboard (140 Wire) — Connections (140-wire set)
• Water Turbidity Sensor Module — Turbidity (water-cloudiness) sensor
• pH Analog Sensor - Acidity Meter for Arduino — Full pH / acidity probe

How the idea works

Every part in the kit has a job. Assembled in the right order they stop being loose parts and become a working system — one you build yourself, understand at every step, and see the result of with your own eyes. The included build guide walks you from zero to running.

Your journey: from kit to competition

• Build — assemble the kit and get it running.
• Understand — learn why each part is there and how it works.
• Improve — modify it, add a sensor, tune it, try your own idea.
• Make a project — turn the experiment into a project that solves a real environmental problem.
• Compete — enter your project into local and international competitions.

A good fit for tracks such as:

• Water / المياه

What you'll learn

• How sensors measure water purity (TDS), temperature and turbidity
• Reading analog sensors and converting signals to real units
• Comparing water sources with real, side-by-side data
• Why clean water is one of the planet's biggest challenges

Extend & innovate

Add the turbidity sensor to measure cloudiness and the pH probe for a full acidity test — turning this into a complete water laboratory. Log readings to a phone over WiFi, build a map of water quality in your area, and present it as a science-fair project.
