Excerpt giving rough description of this handheld type reads as follows:-
In another design, known as optoelectronic, spinning cups turn a kind of paddle wheel inside the metal canister underneath. Each time the paddle wheel rotates, it breaks a light beam and generates a pulse of current. An electronic circuit times the pulses and uses them to calculate the wind speed. The anemometers shown in our photos up above, made by Ames of Slovenia, work in roughly this way.
Closeup of a basic handheld anemometer with these parts labeled: cups, vane, scale for wind direction, wind speed display, generator, case.
