Introducing The World’s First Handheld Device to Measure Both Wind Speed and Direction
Vaavud is a start-up company from Copenhagen, Denmark, dedicated to building the world’s most efficient and user friendly wind meters. They have recently launched a Kickstarter campaign to crowd source the funding for their new device - the first handheld device to measure both wind speed and direction.
Their first product was a small plastic wind meter that could connect to smartphones via the headphone input. The gadget used sound waves, which were then converted into a wind speed measurement via the Vaavud mobile app. By sharing information from each individual user’s app, Vaavud were able to create a detailed image of wind speed around the world. Vaavud secured over £200,000 of funding from their first Kickstarter campaign to pursue their experimentation with wind, smartphones and electronics-free hardware.
Kickstarter is a website that allows creative projects to find funding from donations given by people interested in seeing a project come to fruition. A Kickstarter project only receives the money pledged if it reaches its full funding target. Vaavud’s current Kickstarter campaign is for an updated device that measures both wind direction and speed.
The new Vaavud wind meter uses an optical sensor able to measure rotations at 40.000 times per second. With the new rotor design being more asymmetrical, the larger part of the rotor accelerates when it hits the wind. By comparing the point with the highest speed against the compass direction, the wind direction is established also.
A working prototype for the new device has been built, but there is still more design work to be done. Vaavud are therefore using Kickstarter to raise £20,000 to continue with the development of their new product.
