There are instruments called Ceilometers which can measure cloud height and cover, but they're not especially accurate for cover (they are quite good for cloud height, especially at night) as a cloud can sit over the instrument and give a false reading. Also, unless cloud passes over them they give a false negative. The best instrument for measuring cloud cover is a trained Mark I eyeball (or two).
An anemometer is the instrument that measures wind direction using a wind vane.
