# Wind Vane

### How the Sensor Works

The wind vane uses the [**AS5600**](https://drive.google.com/file/d/1f8m0zBGUlcEmwGa42xqODvVKy_ajvcer/view?usp=sharing) magnetic encoder to measure the angular position of the vane as it aligns with wind flow. Direction is sampled every second and combined with wind speed data to form vectors. These vectors are averaged over 60 seconds to calculate the mean wind direction, while the peak gust direction is determined by averaging the three vectors corresponding to the highest 3-second wind speed period.
