obtains its data from a weather station located 5 miles to the west of
Chipping Campden itself. The
station is a Davis Vantage Pro. The added advantage of the davis
vantage pro is that it is a wireless setup in that the sensors can be
positioned anywhere outside and the data can then be transmitted back
to the console via radio link. The console can then display this data.
The wireless sensor suite contains an anemometer, temperature sensor,
humidity sensor and a rain bucket. Pressure is sensed from the console.
The wireless sensor suite is powered by solar power. A solar pannel is
located on the back which needs to be positioned to the South in order
to collect enough sunlight to get a good charge. For night time use or
on days where there has
been very little sun there is a back up battery installed which has a
service life of approximately 2 years.
The console itself is powered via a mains adapter but in the event of a
power cut there are back up batteries installed enabling continued
reception of weather data. The console also has a data logger installed
which allows you to connect the console to a PC for data logging. If
the computer is off the data logger unit will continue to log the data
at set intervals until the computer is reconnected and can download the
data off it.
The console is connected to a computer via a serial cable where a
software package called Virtual Weather Station obtains the data from
the console. The version I am running is Virtual Weather Station
Internet Edition. This has many excellent facilities such as providing
the data to this website and also supplying data in real time to
Weather Underground using Rapid Fire.
The Vantage Pro weather station has so far being running for 6 years
and has to this date had no major problems or failures. One minor
problem has been the incorrect reporting of rainfall. The sensor suite
was over reporting rainfall which I think was down to an obstruction on
the tipping buckets. Since removing it there has been no further
