Anemometer used for the automatization of the garden sliding shade. Basically, print 3 cups, then print the cover, insert the cups into the openings within the cover and apply the thin CA glue to fix it. Print the tower and insert the bearing 608ZZ into the tip of the tower. Once it's done, the cover with the cups can be inserted into the bearing as well, allowing the smooth operation.
Once it's assembled, drill the 5mm hole through the cover and the tower, insert the 5x4mm cylinder magnet into the cover and fix it using the thin CA glue, use the drilled hole in tower to mount there the hall sensor that will sense the magnet each time it passes. Secure the hall sensor with the silicone to make it water resistant.
Use the hole at the bottom of the tower for the wire, allowing the connection to the rest of the automation system.
