Which instruments measure wind speed and wind direction?

Measuring wind speed and wind direction uses two different instruments because wind has both a speed and a direction component. An anemometer is used for wind speed; its cups or propeller spin faster as wind speed increases, and that rotation is translated into a wind speed value. A wind vane (weather vane) measures wind direction by aligning with the wind and showing the direction from which the wind is coming. Together, they provide the full wind vector: how fast and from which direction. Other instruments like a barometer, thermometer, and hygrometer measure pressure, temperature, and humidity, not wind.
