Mjolnir

The wind meter Mjolnir is the first product of the young Danish company Vaavud. The product has been succesfully sold within a year in 96 countries. This compact wind meter connects with the samrtphone via the headphone jack and then measures the wind speed in less than 30 seconds with the help of a special app. The device is made for surfers, kite surfers, sailor, and golfers as well for all those who deal with the weather or have a hobby such as paragliding where wind plays an important role. Also for event organizers or climatologists the device is extremely useful.
The wind meter Mjolnir works like an anemometer and functions completely without any electronics. The secret lies in the magnet that cooperates with the compass in the smartphone. The signal is measured and then converted into wind speed.
The Mjolnir - the name comes from Thor's hammer; Thor is the God of thunder and his hammer is a no frills tool that is very good at what it does, and it is virtually unbreakable - is plugged into the headphone jack of your smartphone and the two magnets produce a magnetic field that is detected from the smartphone. The app works with a special algorithm, calculates the windmill rotation quickly and shows how strong the wind is blowing. Measurements can also be made when the smartphone is offline or when no signal is available. The measurements are then shown automatically as soon as the smartphone is back online on a special map in the app. The free app can be downloaded in the iTunes App store or google play and displays the average and maximum wind speed. Users can choose from different units (knots, km/h and m/s).
The wind meter is ruggedt, stable and ideal for traveling. The information of the measurements will be automatically loaded on a card and other users can access this data. All personal information is anonymized.
