About This Station
The station is powered by a "Davis Instruments" Vantage Pro 2 Plus weather station. The data is collected every 2-45 seconds (depending on the sensor) and most of the site is updated every 5 seconds. This site and its data is collected using Weather Display Software. The station comprises of an anemometer, rain gauge accurate to 0.2 mm increments, an indoor thermo-hydro sensor, and an outdoor therm-hydro-barometer sensor, situated in optimal positions for highest accuracy possible.

Data is also being submitted every 6 secs to several other Amateur Weather observation sites. These websites are a collection of a number of personal weather stations collectively submitting their data for the public to view in realtime - as it happens, not just predictions.

Outdoor Temperature Sensor/Rain Gauge
This is location for the main sensor suite that records external temperature, humidity, rainfall, UV and Solar, and is referred to (by Davis and myself) as the "Integrated Sensor Suite" or "ISS" for short. Atmospheric pressure is recorded by the indoor temperature sensor, contained within the main console which sits in the family room inside the house. The ISS is located on the north side of the house, and while subject to direct sunlight (and as such, solar radiation and heating), has a Fan Aspirated Radiation Shield (or Stephenson Screen) to prevent sunlight radiation heating and inaccuracies in the readings. The FARS operates 24x7 and uses a combination of solar power and batteries (for nightime, charged by the solar panel), and maintains VERY accurate readings throughout the 24hour period. the unit is located over a natural grass surface to prevent additional solar radiation, and is also placed at the extreme edge of my deck roof to prevent heated air (from the deck) leaching into the unit and effecting the accuracy of the readings. There is also a PVC blind (seen to the left of the picture) that prevents additional hot air escaping from the deck and effecting the readings (although, if the missus asks you, the blind is to allow us to use the deck all year round .. nothing to do with the weather station at all... OK!!
The Rain-Gauge (Black cylinder on top of the ISS) is located in a very good position, and does not get influenced by nearby trees, buildings, or structures.
Anemometer
The Annemometer is located on my Antenna mast, approx 7.5 meters above ground level. The unit transmits wind information (via the wireless unit located just above the first cross-bar) every 2.5 seconds. Although it is in the best position possible on the house, it is still subject to mechanical turbulence (i.e. shielding) by dual-level houses in the North-West, South,and North areas. Due to an inconsiderate (and after many discussions, some would say unreasonable) southerly neighbour, I am prevented from rectifying this and the current location will probably serve as the units long-term position.
About This Location
Heidelberg (including Bulleen, Templestowe, Doncaster East, Park Orchards, Bundoora, South Morang, Yan Yean, Whittlesea and Yarrambat) is a suburb of Melbourne famous for its association with the Heidelberg School of painting. Heidelberg is located 18 km by road north-east of Melbourne's CBD and 80 m above sea-level. The Yarra River forms the eastern boundary of the City of Heidelberg which incorporates the suburbs of Banyule, Eaglemont, Ivanhoe, Darebin, Rosanna, View Bank, Macleod and Yallambie.
Heidelberg was declared a city in 1931, and in 1994, after the State Government merge of local councils, was renamed the City of Banyule. West Heidelberg was opened up when the Housing Commission contracted A.V. Jennings to subdivide the area in 1945. The Olympic village was built there in 1956 to provide accommodation and training for Olympic competitors. In recent years, some light and general industry has been established at West Heidelberg although the character of Heidelberg, as a whole, is primarily residential. However, it has retained pockets of the natural beauty which made it such an attraction in the 19th century.
