The rugged and electronic-free Vaavud-1™ wind meter (also known as ‘Mjolnir’) turns your compatible smartphone into a high-tech meteorological tool, measuring wind speeds up to 48 knots with near-professional precision. Its unique design and electronic-free technology provide durability and reliability to meet the demands of an active life. Due to it’s ruggedness, Vaavud calls this device ‘the world’s toughest wind meter’. The powerful Vaavud™ App provides an extremely easy to read and user-friendly interface, and new, useful features are constantly added to the app.
Design
With its compact two cup design, inspired by professional anemometers, the Vaavud-1™ wind meter is accurate, practical and truly pocket friendly. It has a one piece durable plastic rotor and low friction PTFE bearing. Reliability and long service life are assured through the use of revolutionary electronic-free technology, communicating directly with the magnetic field sensor in your smartphone.
Vaavud App
The Vaavud-1™ App measures and displays wind speed in commonly used units of measurement. It has a neat and clean interface that shows the most important wind characteristics: actual, mean and max wind speeds. The smoothed graph provides additional data on variations in strength as well as a quick overview. Once your measurement is completed the app presents you with a neat summary, which includes barometric pressure, temperature, wind chill and ‘gustiness’ (turbulence intensity). Furthermore, the app features a global live map, and your personal measurement history. The Vaavud™ App is available free from the Apple App Store and Google Play.
Precise
The Vaavud-1™ wind meter has a wind range from 4 knots up to 48 knots (2 m/s up to 25 m/s). Accuracy is the lower of +- 4% and 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.
Compatible with Smartphones and Tablets
The Vaavud™ wind meter application works on iOS or Android devices. The electronic-free signal transfer utilizes the magnetic field sensor, often called a digital compass, in your phone or tablet.
*Samsung Galaxy S2 Magnet Insert Replacement: When used with a Galaxy S2 phone, the standard four magnet insert in the Vaavud™ wind meter must be replaced with the two magnet insert included in the box. A video showing how this is done can be found under the SUPPORT tab on the Ronstan web site www.ronstan.com. Note, this may also apply to certain other phones as well. For an updated list see www.ronstan.com
*To all Sony device users: Please note that due to Sony’s special hardware configuration (microphone and audio output), the Vaavud 2 device will not work with your phone. The difference is unfortunately more complex than the circuit configuration itself, we experienced lower voltages in the ground and mic connections on sony phones in comparison to Samsung/Apple phones.
