The purpose of this dissertation is to create a sensor based application on Android platform that visualizes data from an anemometer and provides a backend application to store data generated during use of the application.
Anemometers and the data they provide, such as the strength and direction of the wind, are important for sailors. Nowadays, more and more wireless technology using anemometers is on the market. With these devices, you can connect to any smartphone so the data provided by the instrument can be accessed by virtually anyone who is near such an instrument.
As smartphones are very widespread today, there are phones with almost every sailor when they are sailing. So far, the usual scenario was that a complex wind instrument coupled with an expensive display can only display wind data for the sailor who using it. However, if you can display the currently measured values on the phone, it greatly simplifies access to data, as there is only one phone and an anemometer which capable of wireless transmission enough to extract the data.
In addition, the other great advantage of phones is that they can communicate over the internet, not like local wind instrument units on sailboats. This way, the data you receive from your phone can be stored on a single server, so that a large number of data will be available at a later time.
The generated data can provide valuable information to its recorders. The combined knowledge of the current location, direction, speed and wind parameters can be helpful in analyzing post-sailing competitions to provide accurate data to understand what happened during the race.
