Overflow Prevention Tank Valve Kit with Arduino Uno + Ultrasonic
Arduino Uno Overflow Prevention Tank Valve Kit — Auto-Stop Water Wastage
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 never worrying about your overhead water tank overflowing again. With this kit, you'll build a real-world automation system that uses an HC-SR04 ultrasonic sensor to measure water level and triggers a relay valve to shut off the supply when the tank is full. It is a practical project that combines Arduino programming, sensor data, and actuator control — skills essential for smart home solutions and a great way to understand how embedded systems conserve resources.
What You'll Build
You will assemble a working prototype of an automatic tank overflow prevention system on a breadboard. The ultrasonic sensor continuously measures the distance to the water surface, and when the level indicates a full tank, the Arduino Uno signals the 5V relay module to close a solenoid valve (simulated with the included LEDs). Red and green LEDs provide clear visual alerts for valve status, making it easy to test and demonstrate the logic before connecting to an actual water line.
What You'll Learn
- Interfacing the HC-SR04 ultrasonic sensor with Arduino Uno and reading accurate distance data
- Implementing threshold-based logic to trigger actions when a tank reaches full level
- Controlling a 5V relay module for high-power switching, including flyback diode protection
- Building a complete home automation subsystem on a breadboard with indicator LEDs

Who This Kit Is For
Ideal for CBSE Class 11-12 students working on physics or computer science projects, B.Tech first-year ECE/EEE students exploring embedded systems, and participants in ATL Tinkering Labs or Smart India Hackathon. It is also a perfect hands-on kit for hobbyists and makers at IITs, NITs, VIT, or BITS who want a reliable home automation prototype without hunting for individual components.
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 open the AI build companion — it offers real-time, step-by-step guidance. You can also message us on WhatsApp for direct human support; we stay with you until your tank valve controller works.
Does this kit include a water tank or solenoid valve?
No, this kit provides all the electronics to build the controller. The relay module expects an external solenoid valve or pump; you can simulate the valve action with the included LEDs. For a full demo, add any standard 5V solenoid from your lab.
Can I use this kit for other level sensing projects?
Absolutely. The ultrasonic sensor and relay module are versatile — you can adapt the same hardware to build a distance alert system, automatic room light, or obstacle-avoiding robot with minor code changes.
Do I need prior Arduino experience?
Basic familiarity with the Arduino IDE helps, but the AI companion provides pre-written code and wiring diagrams. This project is intentionally intermediate — it bridges the gap between simple LED blink sketches and real‑world automation.
HC-SR04 ultrasonic measures tank fill level and closes relay solenoid valve when full.
