Oregon Scientific STC800 Solar Cell for WMR200 / WMR80 Weather Station Review:

For WMR200 Weather Station users:

This a additional solar cell for the WMR200 sensors. This solar cell is great for people who chose to install their temperature and humidity sensor in a different location to the wind vane.

For WMR80 Weather Station users:

A great addition for the WMR80 to power the wind vane, this means battery charging is not required. One thing to take into account is that to solar power the temperature and humidity you will also require a THGN801 sensor.
