These measure wind speed. You can build a DIY version using paper cups, straws, and a pencil. As the wind blows, the cups spin, and the rotations per minute can be calculated to determine speed.
Simple tools like a weighted index card can also serve as basic indicators of wind force. 3. Harnessing Wind for Energy
To understand wind, we must measure its speed and direction using specific instruments:
