Smart Leak & Flood Detector Kit

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

Build a tiny guardian that watches for water where it should not be. Place sensors on the floor near a washing machine, under a sink, or beside a water tank — the instant a leak touches them, an alarm sounds so a small drip never becomes a flooded room. It is your first real-world safety device, and it teaches how a single drop of water can be turned into an electrical signal.

What's inside the kit?

• Raindrop Water Sensor ×2 — Water-contact sensors — place where leaks happen
• XKC-Y25 NPN Intelligent Non-Contact Liquid Level Sensor — Non-contact level sensor — watches a tank from outside
• Piezo Element - 20mm Sensor — Piezo alarm — sounds the instant water is detected
• Arduino UNO Rev3 SMD Chip (SMD35) - Clone — Arduino UNO — the brain that reads and reacts
• BB-01 Breadboard 830 Tie Point — Breadboard for wiring
• BB-J65 Jumper Wires for Breadboard & Arduino (65 Wire) — Jumper wires
• Clear Acrylic Case for Arduino UNO — Clear acrylic case for the controller

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 a water-contact sensor closes a circuit when wetted
• Reading a digital sensor and triggering an alarm in code
• Adding a non-contact level sensor to watch a tank from outside
• Designing a reliable early-warning safety system

Extend & innovate

Add Wi-Fi (with an ESP board) to send a phone alert, log every leak event with a timestamp, or wire a relay to automatically shut a valve. Map the wettest risk spots in your home.
