- Measures seawater pH and temperature in real-time
- Generates electricity from solar and wave energy
- Equipped with solar panels and a wave energy harnessing system
- Electricity stored in batteries for powering oceanographic equipment
Technology Highlights
- Solar panels installed on top of the buoy
- Wave energy harnessed through buoy movement
- Combined energy sources ensure continuous operation
- Real-time data accessible for research and conservation purposes
Applications and Benefits
- Supports marine conservation efforts
- Provides accurate and timely oceanographic data
- Helps monitor environmental changes around Koh Man Nai
- Promotes the use of renewable energy for research purposes
