measures air temperature

measures humidity in the air

An anemometer is a device used to measure wind speed. It typically consists of small cups or blades that rotate when exposed to wind. The rotation speed is then converted into a wind speed measurement. Anemometers are commonly used in meteorology, aviation, and other industries where wind speed is important for safety and monitoring purposes.

While anemometers primarily measure wind speed, certain types of anemometers can also measure other meteorological parameters. For example, a hot wire anemometer can also measure air temperature and humidity in addition to wind speed. However, measuring air temperature, wind direction, air pressure, and humidity typically require separate instruments or sensors.
