The latest WaveDroid test deployment off the Durban coast has yielded very encouraging validation data. Check out the comparison graphs between WaveDroid and a nearby reference buoy. RMS Error in significant wave height of 6.4 cm. The spectrograms (development of 1D spectrum over time) look very similar.
The first goal of H-max is the development of a smartphone-based wave measurement buoy, coined WaveDroid. Relying on low-cost but accurate smartphone sensor data, WaveDroid achieves a significant cost reduction compared to conventional wave measurement buoys. As the phone provides 3D sensor data, directional wave data are literally in your pocket. Employing the phone's internet connection, real-time data make their way to your desktop through e-mail, FTP or online database. The ever increasing phone network reception rates in coastal areas all around the world make WaveDroid the wave measurement buoy of the future. The first field tests are showing more than promising results, proving that even the accuracy of smartphone-based wave measurement buoys meets industry standards!
