Springville Networks Weather Station
The
choice of the WX-200 as a weather station was primarily because of its
low cost. It was put in operation in 1997 and for two years its data was available only
sporadically, mostly as monthly reports.
In July 1999 it began publishing its data on the Internet live and full time.
The reason for its existence is because Fortuna's weather, widely available on the Internet as well as the
Weather Channel, is measured at an airport an hour's drive north, situated on a much cooler
and often foggy Pacific shore. Because Fortuna is sheltered from the cold Pacific winds
it may be ten or fifteen degrees warmer.
The station.
The wooden weather shelter seen below is next to the asparagus bed and contains the temperature
and humidity sensors, a mechanical high/low thermometer and a thermometer with a soil probe.
The rain gauge is mounted on the top of the shelter.
A steel pipe with a very heavy chunk of concrete on one end (a parking meter post for twenty years) was recycled to neatly hold up the aluminum anemometer
mast, which weighs all of nine pounds including the wind sensors.
One hundred and twenty feet of Cat5 cable inside buried PVC pipe connects everything to the
Springville Networks weather computer. When your browser requests information, the sensors and database records are queried and a page is put together and sent on its way to your screen, all done at the speed of light.
The system is quite sensitive - on a cool day, placing your hand inside
the shelter for just a few seconds will put a quarter-degree wobble on
the temperature graphs.
These pictures were taken in December, 2000.

This is the sensor shelter with the rain gauge unit on top. It's bolted to a
five-foot stand to bring it to eye-level. It's also in the middle of a 40 by
50 foot yard, with a dwarf apple tree twelve feet away. The telephoto lens
compresses the space - I took these two pictures from twenty feet away.

The anemometer and wind direction
unit is 22 feet high. This make a great lightning rod and RF attractor,
so the unit is electrically grounded.
