World’s first handheld wind meter that measures wind speed and wind direction

I am glad to publish the following press release by the Danish company Vaavud.

This device seems very interesting for any multirotor user in order to better assess flight conditions.

Here we go!


The Danish company Vaavud that created the world’s first electronicless wind meter that transforms your smart phone into a high-tech meteorological tool, is now ready to ship their second generation wind meter.

The new Vaavud anemometer called Sleipnir (or Vaavud 2) leverages the company’s proprietary technology, knowledge about wind speed measurement and adds the ability to measure wind direction. The Sleipnir device has an asymmetrical rotor with a sensor that performs 40,000 measurements per second and draws power from your smartphones’ headphone jack. The rotor design means that it will accelerate just as the wind hits the largest area, and then decelerate again. The ultra precise sensor can measure these subtle variations in speed, and compare the point of maximum velocity to the compass direction and thereby give the wind direction.


The Sleipnir device and the Vaavud brand in general has been in the top 50 finalists last January at the high profil Brand New Award that is part of the annual ISPO exhibition in Munich – the world’s largest exhibition within the sports and outdoor industry. Sleipnir received the prestigious Reddot Design award 2015 held annually in Singapore.

Many more features will follow in the coming months to answer Vaavud community’s need. They already have active drone users, sailors, golfers etc.

The popular Vaavud app, available for both iOS and Android and also compatible for Sleipnir, has been downloaded more than 130.000 times. It represents 10.000 weekly measurements covering more than 170 countries.

The app delivers a clear overview of average, actual and maximum wind speed that you can read with three different innovative screens. It also contains a global live map, your personal measurement log, a summary screen that provides additional data such as temperature, wind chill, barometric pressure and a gustiness index – a measure for how unstable the wind is. Many more features will follow in the coming months to answer Vaavud community’s need. They already have active drone users, sailors, golfers etc.

“After receiving lot’s of positive user feedback for our first device, Mjolnir (or Vaavud 1), we are really pleased to be launching Sleipnir to provide even better features. It will be great to see people put it to use and hear their feedback” says Thomas Helms CEO and co founder. “

We really believe that our unique ability to measure and see fluctuations in wind direction will be useful for many people. We look forward to keep developing new innovative software features that exploit this function.” Sleipnir, which is available in black and red, is retailed for $60 in the USA and €55 in Europe and the rest of the world. It is available on the Vaavud webshop ( and in a wide range of retail stores throughout the world.
