Wave Buoy 'Wave Elf' Mini

The Wave elf (mini) is a small marine observation buoy with advanced wave sensors 2.0, which can be anchored or drifted to achieve short-term observation of waves at sea and provide stable and reliable data on wave elements such as wave height, wave direction and wave period. The data is transmitted back to the client via 4G, Beidou, Tiantong or Iridium.

Equipped with a new version of the Wave Sensor 2.0

Built-in highly efficient ARM core processor and patented optimised algorithms for measuring wave height, direction and period.

Small in size and light in weight

The buoy body is approximately half a metre in diameter and is lightweight, making it easy to transport and deploy. 

Multiple communication methods

Wave data can be transmitted back to the client in real time via a variety of methods including BeiDou, Iridium and 4G.
