Smart Buoy (Client)

oneM2M Application Entity

This project contains the client code for the Smart Buoy. It collects real-time wave data using multiple sensors:

• Accelerometer: Measures wave motion (used to estimate wave period).
• Ultrasonic Sensor: Calculates wave height.
• GPS Sensor: Provides location information.
• Temperature Sensor: Records sea surface temperature (SST).

Collected data includes: Wave Period, Wave Height, Location, and Sea Surface Temperature.

🚀 How to Run

1. Configure the Settings
   Open the config.ini file and adjust the parameters under the following sections:

   • CSE SERVER: Set the IP, port, and CSE base for the oneM2M server.
   • BUOY: Specify the buoy name and mock mode.
   • SENSORS: Enable or disable individual sensors.

2. Install Dependencies
   Make sure you have Python 3.x installed.
   You may also need requests and other libraries:

   pip install requests

3. Run the Application
   Execute:

   python main.py

   This will:

   • Check and register the AE (Smart Buoy) in the oneM2M CSE server.
   • Create necessary Containers for each active sensor.
   • Collect sensor data periodically and create CIN resources on the CSE server.

📌 Notes

• If mock is set to TRUE in config.ini, the client uses mock sensor data.
• If you have real sensors, implement and enable the real_sensors.py accordingly.
• Make sure the oneM2M CSE server (e.g., TinyIoT) is running before starting the client.
