Anemometers were first made in 1450 by an Architect called Leon Battista Alberti.

The first ever Anemometer made was a mechanical anemometer. An Anemometer is an object which measures wind, in this time and age the Anemometer is most commonly used by weather stations.

The cup Anemometer was made very late after then original mechanical anemometer. The cup anemometer was made in 1846. The three cup anemometer produced by Canadian John Patterson in 1926 (very long after the original cup anemometer was made) and subsequent cup improvements by Brevoort & Joiner of the USA in 1935 led to a cupwheel design.

Sonic anemometers were first developed in the 1950s, they use ultrasonic sound waves to measure wind speed. They measure wind speed based on the time of flight of sonic pulses between pairs of transducers.

This is a type of a homemade anemometer usually people make their own anemometer to measure the speed of the wind in a local area. With a homemade anemometer you measure the speed by how many times it turns
