A Danish group of entrepreneurs has developed a wind meter for iOS or Android smartphones. The Vaavud wind meter is made of high performing plastics and has no electronic parts.
The device has a wind range of 1 m/s up to 25 m/s, and has been tested and calibrated in a professional wind tunnel at the Technical University of Denmark. The plug-in device is easy-to-use and uses the smartphone's headphone jack. As the wind pick up the two cups, the Vaavud starts to spin and then data is transmitted to the smartphone. "The secret is two small magnets in the rotor. The magnetic field sensor in the phone can detect when they rotate, and by using algorithms normally used for sound processing, the rotations can be converted to wind speed". Windsurfers and kitesurfers may upload their readings to the Vaavud website and share all wind speed data with the entire world.
