Weathervane reports via Ruuvi multi sensor bluetooth.

A proof of concept for a Ruuvi enabled weathervane.

The Bluetooth reporting Ruuvi Environmental sensor includes an accelerometer which reports not only the movement of the Ruuvi, but also it's orientation when it is stationary (over a short time period). Using a simple gear set (provided by my 40 year old son) to change the revolving action in the vertical axis to rotating of the Z axis. The Z axis accelerometer value indicates the orientation and the direction of the wind can be resolved.

Notice that as the wind vane revolves the Ruuvi rotates correspondingly.
