There are multiple ways of calculating significant wave height (Hs). According to wikipedia, the original definition was the average of the highest 3rd of waves. What this means is you would measure wave heights(trough to crest) for a set period, order that dataset from lowest to highest, take the top 3rd of the values and…
For many applications, sending serial data from a microcontroller to a computer is easily achieved using one of these serial to USB adapters: For a recent project the microcontroller in question was mounted on a rotating arm so using a normal wired usb to serial adapter was out of the question. Here is a short…
This post will detail an experiment in which the wave sensor was attached to a rotating arm at three different diameters. These diameters were 40cm, 60cm and 80cm. For each diameter, measurements were taken at two speeds to get an idea of how rotation frequency affects measurement accuracy. This gives a total of 6 sets…
Post #5 outlined the steps used to go from vertical acceleration to vertical displacement and how the results were completely off. The reason why each of the displacement graphs at the end of the post look so totally different just by changing the integral reset points is because of a negative offset to the velocity…
