Anemometer
A tool that measures wind speed
An anemometer is an instrument used to measure the speed and direction of wind. It usually consists of cups or vanes attached to a shaft that spins as the wind passes through, and the speed of rotation is measured either mechanically or electronically. The faster the wind speed, the faster the cups or vanes spin. The data collected by the anemometer can be used to determine the average wind speed, maximum wind speed, and wind direction. This information is useful in a variety of fields, including meteorology, aviation and engineering, where understanding wind patterns and behavior is important for safety, planning and design.
