Boat Hull Water Depth Sensor Kit with Arduino Nano
Build a Waterproof Boat Depth Sounder 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.
Navigate shallow waters with confidence. This kit lets you assemble a compact depth gauge that mounts to a boat hull and uses a waterproof ultrasonic sensor to measure water depth in real time. The readings appear clearly on a crisp OLED display, making it an essential tool for fishing trips, lake explorations, or coastal cruising.
What You'll Build
A self-contained boat hull depth sounder. The waterproof HC-SR04 ultrasonic sensor sends and receives sound pulses through the hull or directly in water, calculating distance to the seabed. An Arduino Nano processes the signal and drives a 0.96-inch OLED to show depth readings instantly. The entire assembly fits inside a waterproof enclosure, ready to be secured to your boat.
What You'll Learn
- Soldering components onto a prototyping PCB securely
- Interfacing a waterproof ultrasonic sensor with Arduino Nano
- Displaying real-time sensor data on an OLED screen
- Designing a water-resistant enclosure for marine electronics

Who This Kit Is For
Young makers and boating enthusiasts across India. CBSE and ICSE students can use it for science projects or ATL tinkering lab challenges. B.Tech ECE/EEE learners get hands-on experience with ultrasonic sensing and embedded displays. It is equally ideal for hobbyists building a custom depth sounder for fishing boats, kayaks, or remote-controlled vessels.
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 to chat with the AI build companion, or reach us on WhatsApp. We'll help you debug in minutes, not days.
Is the ultrasonic sensor truly waterproof?
Yes, the HC-SR04 Waterproof sensor is sealed for immersion. It can be mounted through the boat hull or hung over the side in fresh or saltwater.
Can this depth sounder work on a moving boat?
The sensor updates readings many times per second, yielding accurate depth even while slowly cruising. Sudden high-speed planing may introduce brief signal loss.
Do I need programming experience?
None required. The kit includes pre-written Arduino code you can upload with a single click. The AI companion explains each line so you learn as you build.
Accessibility - HC-SR04 waterproof ultrasonic measures water depth from boat hull. Nano shows depth on OLED.
