At that price maybe use two: one for wind speed and another for direction?

I got a similar board through Kickstarter. Got me thinking...

The amplitude would be proportional to the wind speed and the plane it rocks in would would probably be good for direction, though there would be 180 degree ambiguity. Maybe the swing would be a bit higher when downwind.
