Introduction
This is the documentation for the WindNerd 3D-printed anemometers: wind stations you print, assemble and install yourself.
The products
- WindNerd One and One-S: Wi-Fi sensor boards that measure wind speed and direction and upload it over your home network. The One-S adds an Eco mode for battery and solar operation.
- WindNerd OnSpot: a cellular sensor board that uploads over the LTE network, for spots without Wi-Fi.
- Sunbank 2W: a solar power base with battery, for fully wireless installations.
The WindNerd Core (dev board) is documented in a dedicated GitHub repository.
