Ocean Buoy Data Logger
Arduino-Powered Ocean Buoy Data Logger Kit: Water Temperature, Air Pressure, and Wave Height Monitoring
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 deploying your own marine-grade data buoy that captures ocean temperature, atmospheric pressure, and even estimates wave height — sealed in a waterproof enclosure. This advanced kit provides all components to build a self-contained logger for oceanographic research, environmental monitoring, and IoT climate studies.
What You'll Build
You'll assemble a rugged, battery-powered Arduino Uno R3 data logger housed in a waterproof enclosure. Dual DS18B20 temperature sensors monitor water temperature at two depths, a BMP280 measures air pressure, and an MPU6050 IMU estimates wave height via acceleration analysis. All data is time-stamped by a DS3231 RTC and saved to a MicroSD card. A 0.96-inch OLED shows live readings, while a TP4056 module keeps a 2000mAh LiPo battery charged for autonomous deployment.
What You'll Learn
- Implement multi-sensor data fusion using Arduino — combine temperature, pressure, and motion data into a single logfile
- Design and waterproof an enclosure with cable glands for submersion-tolerant sensor probes
- Program an MPU6050 accelerometer to estimate wave height by double-integrating acceleration over time
- Integrate a real-time clock, SD card, and OLED display to build a standalone field-deployable data logger

Who This Kit Is For
This advanced kit is designed for B.Tech ECE, EEE, and Mechatronics students tackling environmental monitoring capstone projects or participating in Smart India Hackathon challenges. It’s equally relevant for early-career researchers at IIT, NIT, VIT, and BITS Pilani who need a plug-and-play oceanographic data logger prototype. ATL Tinkering Lab mentors can adapt it for high-school ocean awareness programs, though the build demands soldering and Arduino proficiency.
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 talk to our AI companion trained on this exact kit. It understands every wiring detail and code snippet, and our team is also on WhatsApp for real-time support.
Can I deploy this buoy in saltwater environments?
The waterproof enclosure and cable glands provide temporary submersion protection, but for prolonged saltwater use, we recommend additional anti-corrosion treatment on connectors and sealing points.
Does the kit include example code for wave height estimation?
Yes, the AI companion provides custom Arduino sketches that demonstrate double-integration of MPU6050 data, along with calibration routines to reduce drift.
How long will the battery last during field deployment?
With a 2000mAh LiPo and power management via TP4056, you can expect approximately 6-8 hours of continuous logging with the OLED active. Turning off the display extends runtime significantly.
Waterproof DS18B20 water temp, BMP280 air pressure and IMU wave height estimate logged to SD. Housed in sealed enclosure.
