Anemometer

An anemometer is a device used for measuring wind speed, and is a common weather station instrument. The term is derived from the Greek word anemos,which means wind, and is used to describe any wind speed measurement instrument used in meteorology . The first known description of an anemometer given by Leon Battista Alberti in 1450.
