If you really want to "wow" your professors...and make a truly useful wind meter, then,
you should design the app to judge the "quality"of the wind.
The wind could be rated on a scale of one-to-ten for "quality".
and if you want to really impress us kiteboarders,
than you should be able add a Jumping Hight to 20m or 60 feet hight with a combined Hang Time Meter.
The calibration maybe could be zero-ed before the session
and should be rated within a foot of accuracy.
It should be able to record all the hight and Hang-time of a session
and compare with others who had the highest boost and Hang Time as a competition.
Don't forget there are some apps already available like the iPhone Wind Meter
which is not that bad, I have on my iPad.
But myself I'm using the Windscribe which I think is the most accurate,
since it measures the velocity of the molecules without any moving parts.
Good luck for the project and don't forget you need to use some
new feature what nobody thought of yet.
For example a remote wind speed indicator which could take a pic every 5 minute
and load it to the web so people wouldn't get skunk and drive when there is no wind
