How an Anemometer Works - Wind Speed Measurement Explained #10001 (License: Personal Use)

This diagram depicts a standard cup anemometer, where wind rotates three or four hemispherical cups attached to horizontal arms, spinning around a vertical axle. The rotation speed correlates with wind velocity and is converted into digital readings via a sensor or encoder. The design ensures accurate measurement regardless of wind direction due to its omnidirectional symmetry.

Used in weather stations, educational science materials, and meteorology guides to explain wind measurement principles; targets students, educators, and weather enthusiasts seeking foundational knowledge.
