This is a new “electronics-less” device by Vaavud, located in Denmark. It consists of a rotor that plugs into the headphone jack of your smartphone and, with a simple app, displays wind speed information. It is also GPS enabled and easily connects to Weendy, so you can share your information with the world. Welcome to 21st century hand-held wind speed monitoring.
The Vaavud wind meter works with iPhone, iPad et sous Android.
The Vaavud app uses the magnetic field sensor that is built into all modern smartphones. The wind meter itself contains no electronics; just a couple of small magnets. The rotations are then measured with the magnetic field sensor and converted to wind speed the technology is Patent Pending
The Vaavud anemometer is very durable, and in the unlikely event that sand, dirt, etc. should get into the moving parts the snap-fit design allows for easy disassembly by the user for cleaning with water. The electronic-less design also means fewer moving parts and less chance of failure. The spinning cups are insensitive to the direction of the wind, regardless of how the user holds the device.
