A mostly 3D printed wind vane is printed with the base attached to a ball bearing and magnet so that the four hall sensors positioned in a “plus” configuration at the base can detect direction.

A wind vane is actually an example of a good sensor giving ‘noisy’ readings: not that the sensor itself is noisy, but that wind is inherently gusty and is constantly changing direction.

Debris and insect meshes help keep the instrument clean. Cup anemometer with separate wind vane - Uses three cups to measure wind speed, while a wind vane measures wind direction. The vane always ...

For example, an anemometer measures wind speed, and a thermometer measures temperature. A wind vane shows which direction the wind is coming from and a rainfall gauge measures precipitation ...
