While we Chinese are now more concerned about air quality and not speed, but air is always better when there is a wind, as sailing enthusiasts, paraglider, and others, to acquire accurate wind speed is the focus of campaigning before the first. Weather station provides wind speed can only be used as a reference because they position determination is not multiple, so Vaavud in Copenhagen designed a cell phone using intelligent instrument for measuring wind speed.

This anemometer needs the support of smart phones, but surprising is, wind instrument itself does not have electronic devices, only the blade has two magnets. Turns out to be a lot of magnetic sensors built into smart phones, by capturing the anemometer turns produces a steady magnetic field around the data to calculate the current wind speed, we have to say that this is a very imaginative solutions. Finally, the measurement of wind speed can also be uploaded to the Vaavud Web site sharing.
