A Vaavud™ wind meter will enable your smartphone to be used as a high-tech meteorological tool. It enables you to take accurate wind readings and works on the most popular smart phones when using the free Vaavud App. There are currently two models with slightly different characteristics available: Mjolnir and Sleipnir.
The design of the Vaavud™ Sleipnir wind meter is inspired partly by professional cup anemometers, and partly by a Danish developed wind turbine with vertical blades. An asymmetrical rotor accelerates slightly when the largest surface is hit by the wind.
The built-in sensor makes 40.000 measurements per second allowing the app to detect even the slightest variations in wind speed. This high frequency signal can be used to derive both wind speed and direction.
