Assembly guide for the wind vane, including magnetic encoder setup and alignment.
The wind vane uses the AS5600 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.
We recently updated the threaded shaft assemblies for the anemometer and wind vane. The new design adds a 12 mm nylon M6 set screw to improve the durability of the anemometer hub and wind vane rotor. Use the latest 3D-printed parts from the GitHub print files page.
