A compass (or nowadays a GPS)
A compass is an instrument containing a freely suspended magnetic element which displays the direction of the horizontal component of the Earth's magnetic field at the point of observation.
An instrument used to magnify sound
An electroscope is an instrument used to detect static electricity.
These two are synonyms. Both speed and velocity are the time derivative of the diplacement. Confusion may come from the fact that these words are sometimes used to describe a scalar quantity and sometimes a vector qty. Proper usage of these would be in the vectorial form, however, it is often used under the scalar form, when direction or orientation is trivial.
Magnitudes that have a direction are called vectors. An arrow can be used to represent them.

To measure the direction of wind, a wind vane can be an ideal tool. A windsock can also be used to measure the direction and strength of the wind.
wind vane
A wind vane in an instrument used for seeing which direction the wind is coming from and which direction the wind is blowing. These 2 things are always the opposite from each other, if the wind is coming out of the SE, then it's going to be blowing to the NW.

The instrument which is used to measure wind is a anemometer. This tool is used to determine the direction in which the wind is blowing.
It's called an "heliostat".
The wind direction is measured with wind vanes or wind socks. The wind speed is measured with an anemometer.
I think it's a seismograph.
