Marine Sensor Buoy Kit with ESP32 + LoRa
ESP32 LoRa Marine Sensor Buoy Kit – Track Grazing, Walking, Resting, Running
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Marine livestock management demands continuous monitoring without disturbing animals. This kit enables you to build a collar-mounted sensor buoy that classifies grazing, walking, resting, and running behaviours using an ADXL345 accelerometer, then transmits event counts to a remote gateway via LoRa. Perfect for field research, CBSE science projects, or B.Tech ECE assignments.
What You'll Build
You'll assemble a compact, weather-resistant buoy with a collar tag that attaches to livestock. The device continuously reads acceleration data, runs a real-time classification algorithm on the ESP32-S3, logs events to an SD card, and sends daily summaries over LoRa to a base station. The result is a functional marine monitoring system you can deploy in ponds, rivers, or coastal pastures.
What You'll Learn
- Classify grazing, walking, resting, and running from accelerometer data using the ADXL345
- Configure LoRa SX1278 long-range transceiver for low‑power data transmission
- Integrate DS3231 real‑time clock and MicroSD for timestamped event logging
- Design a battery‑powered embedded system with TP4056 charging and power management

Who This Kit Is For
CBSE Class 11–12 students undertaking physics or computer science investigatory projects on wireless sensor networks. B.Tech ECE and EEE students prototyping marine IoT solutions for Smart India Hackathon challenges. ATL Tinkering Lab mentors demonstrating real‑world livestock tracking with LoRa. Researchers from IITs, NITs, VIT, and BITS needing a rapid, field‑deployable collar tag system.
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 chat with the AI companion specific to this marine buoy kit. For additional help, WhatsApp our support team — we typically respond within an hour.
Can I use this kit for livestock that are not in water?
Absolutely. The buoy enclosure is water‑resistant by design, but the collar tag works equally well on dry land. You can mount it on any cattle to monitor activity patterns.
Do I need a separate LoRa gateway to receive data?
The kit includes the transmitter end. To view the transmitted data, you’ll need a LoRa receiver — easily built with another ESP32 and RA‑02 module (available separately). The AI companion includes gateway setup scripts.
Is prior programming experience required?
The ESP32-S3 comes pre‑flashed with firmware that handles classification and LoRa transmission out‑of‑the‑box. If you want to tweak algorithms, the Arduino sketch is fully documented and modifiable.
Marine Monitoring — ADXL345 collar tag classifies grazing, walking, resting, running. LoRa transmits event counts to gateway.
