Which instrument measures wind direction?

Explanation:
Wind direction is shown by an instrument that aligns with the airflow. A wind vane has a lightweight arrow that spins on a vertical axis and points into the wind, so the direction it points tells you where the wind is coming from. The other tools measure different things: a hygrometer gauges humidity, an anemometer measures how fast the wind is blowing, and a barometer measures air pressure. So the wind vane is the best choice for indicating wind direction.
