Vaavud Anemometer

Compatibility

The Vaavud wind meter works with all iPhones from 4 and onwards, and all iPads from 2 and onwards, running on iOS 6 or 7.

With regards to Android phones we have currently confirmed it to work with Samsung Galaxy S3 and S4, HTC one and Google Nexus 5, as well as a number of other devices. Check out this post in our knowledge base to see the complete list.

Design

The Vaavud design is inspired by professional cup anemometers, but with two cups instead of three, in order to make it truly pocket friendly. The  one piece, molded rotor and the low friction Teflon bearing makes the Vaavud wind meter extremely durable. If sand or dirt gets inside the Vaavud wind meter it can easily be cleaned out with water. And The Vaavud wind meter can take quite a beating – it is built for action!

The Vaavud app

The Vaavud app gives you a clear overview of average, actual and maximum wind speed, as well as a real time graph – in fact the first real time graph in the world on a hand held anemometer! And you can scroll and pinch-zoom on the graph, if you want to taker a closer look at something.

The unit of measure can be changed on the fly by simply tapping the screen. (Available units: m/s, Kmh, mph, Kts and Bft.)

A live map gives you access to measurements made by other Vaavud users globally. Tap on a measurement to see details and a map thumbnail of the location. Tap on the map thumbnail to zoom in and see exactly where the measurement was made or tap on a nearby measurement on the list to see it’s details.

New features will constantly be added to the app. Measurement history will be available soon, and much more will follow.

Finally, you can use the Vaavud wind meter together with the Weendy app to tap into the world’s fastest-growing  community-based weather network.

Accuracy

The Vaavud wind meter has a wind range of 2 to 20* m/s. Precision is the least of +/- 4% or 0.2 m/s. The wind meter has been tested and calibrated in a professional wind tunnel at the Technical University of Denmark.

Because of the cup-anemometer design, the precision of the Vaavud wind meter is not affected by changes in wind direction (unlike a propeller based anemometer, which must point precisely up against the wind to measure correctly). And the Vaavud app taps into other sensors in your phone, to ensure that the device is held correctly, so the risk of incorrect measurements can be minimized.

*Up to 24 m/s for iPhone 5S and up to 48 m/s on some Android phones
