Weather Station: Wind Vane and Anemometer

The wind part of a complete, modular DIY weather station: a cup anemometer for wind speed and a vane for wind direction, read by reed switches or an AS5600 magnetic sensor.

A real data project: students build the sensors, connect them to a microcontroller, and log and chart the weather at school.

1. Print in PETG (or ASA) so it survives sun and rain outdoors.
2. Choose the reed switch or the AS5600 version of the vane, and print the matching mount.
3. Wire the sensors to an Arduino or ESP32 and count anemometer turns per second.
4. Calibrate against a hand-held anemometer or a car ride on a calm day.
