Wokingham Weather Monitoring Station
(above) overview of station location
The anemometer (which is used to measure the wind speed) and
the weather vane (which is used to measure the direction of the wind)
are both located atop the mounting pole.
The rain gauge (which is a tipping bucket type) is located at the apex of the roof.
The Stevenson Screen (which houses the thermometer and wireless transmitter) is
located on the side of the shed.

Homemade Stevenson Screen details:
The original Stevenson Screen that came with my Fine Offset weather station was not very efficient
as it was too small and did not keep the sun off the temperature sensor, therefore it would heat up
and give a higher reading than expected.
So I decided to make myself a "Homebrewed Stevenson Screen" to upgrade the original one,
(complete with a solar fan to help get rid of heat buildup), which you can see in the images above.
See below for the component list and PDF drawings.
Components
All items were bought from HOMEBASE.
Except the solar fan which was bought online from here:
