Anemometer

Real World Example

Imagine you're trying to gauge how busy a restaurant is just by driving past it. This is similar to how an anemometer measures wind speed by observing how fast the wind causes its cups or blades to spin. Just as the number of cars in the parking lot can help you estimate how crowded the restaurant might be, the speed at which the anemometer's components rotate provides information about the wind's velocity.
