Wind Direction Sensor

HI ! I am trying to build a Wind direction Sensor for a Base Station , but I am searching and looking for diagrams and tips to make it . Can anyone help me or guide me throught this proccess

What mechanical arrangement do you plan to use?

I was thinking in a Hall effect sensor. Maybe if I put a magnet in every direction and attech the sensor in the rotary when it pass over it sends the pulse to the arduino. Just thinking . Which arrangement do u suggest me?

There are compass ics that can tell you what direction a magnet is pointing. Using something like this would reduce the mechanical complexity as you only need a single magnet and sensor.
