Water Level Indicator Kit with Arduino Uno + LED
Water Level Indicator Kit with Arduino Uno & LED – Build a Home Tank Monitor
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 a line of LEDs on your wall that tells you exactly how full your overhead water tank is—no more climbing up to check. With this kit, you'll wire five resistive probes that measure water height and light up graduated LEDs, from empty to full. Built around the beginner-friendly Arduino Uno, the project introduces real-world home automation and sensor interfacing in just a few hours.
What You'll Build
You'll assemble a functional water level indicator that mimics a home tank monitor. Five copper wire probes placed at increasing heights in a small water container (not included) detect water presence through resistance changes. The Arduino reads these values and turns on the corresponding LEDs—red for low level, yellow for mid, green for full—giving you a visual readout just like a real tank gauge. You can later adapt it to monitor sumps, overhead tanks, or even plant watering systems.
What You'll Learn
- How resistive water level sensors work and how to design electrode-based probes
- Wiring simple voltage divider circuits to convert water resistance into digital readings
- Programming an Arduino Uno to read multiple analog inputs and control outputs
- Practical debugging of sensor circuits and interpreting serial monitor data

Who This Kit Is For
This kit is ideal for young learners in CBSE Class 7–10 exploring STEM, ATL Tinkering Lab projects, and beginner Arduino hobbyists. It suits B.Tech ECE/EEE students prototyping simple sensor systems and anyone curious about home automation basics. Even parents can build it alongside children aged 8+ under supervision, making it a great family weekend project.
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 on the box to access the AI companion for instant, step-by-step help. You can also reach us on WhatsApp for one-on-one guidance.
Is the water sensor safe to use in a real tank?
The copper probes are for demonstration only and should not be submerged in drinking water. For real tanks, upgrade to stainless steel probes and waterproof the connections.
Do I need to know coding beforehand?
No, this beginner kit includes pre-written Arduino code that you can upload and modify. The AI companion explains every line so you learn as you go.
Can this kit detect water levels in a sump or underground tank?
Yes, the principle is the same. You can extend the probe wires to reach the desired depth and calibrate the code for different tank sizes.
Five resistive water probes at different tank heights light graduated LEDs showing tank fill level.
