Compatible with smartphones and tablets

The Vaavud™ wind meter application works on iOS or Android smartphones. The electronic-free signal transfer utilises the magnetic field sensor, often called a digital compass, in your phone or tablet. To be able to detect high wind speed this sensor requires a high update/refresh frequency. The following devices have been confirmed as capable with the Vaavud™ wind meter and App, and will function across the full working wind range.

The Vaavud™ wind meter has a wind range from 4 knots up to 48 knots (2 m/s up to 25 m/s). Accuracy is the least of +- 4% or 0.4 knots (0.2 m/s) with testing and calibration confirmed in the professional wind tunnel at the Technical University of Denmark. The cup anemometer design makes the Vaavud™ less sensitive to the way it is pointed; a weakness in impeller type wind meters.
