the cup anemometer is used to find out how fast the wind is blowing.
Simple: I'm guessing they're just anemometers in the form of cup. A cup anemometer is a device with cups that spin as the wind speed changes. So people probably sometimes call it a cup anemometer because it has cups.
A cup anemometer is typically made from lightweight materials such as plastic or metal, with three or four cups attached to the ends of horizontal arms. The cups may also be made of metal or a durable plastic material to withstand weather conditions.
an anemometer is a big pole most likely on top of a house with cup like tubes spinning on top.

A cup anemometer is used to measure wind speed. It consists of three or four cups that catch the wind and rotate. The speed at which the cups rotate is proportional to the wind speed, allowing for accurate measurements to be taken.
The anemometer has no precisely known inventor. The first recorded description of an anemometer was by Leon Battista Alberti in 1450. The cup anemometer was invented in 1846 by Dr. John Thomas Ronrey Robinson.
Use an anemometer. The three cup thing on weather stations that is spinning in the wind.

You need an anemometer.
To calibrate a homemade anemometer, you can compare its readings to a known standardized anemometer in the same conditions. Make adjustments to your homemade anemometer based on these comparisons until its readings are consistent with the known device. Regularly repeat this process to ensure accurate measurements.
