Hardware
The weather station is an Oregon WMR200 with the instruments located on my roof in Bellmere, near Caboolture in South East Queensland, and they are approximately 20m (66 feet) above mean sea level. The receiver is connected to a dedicated PC running as a Database Server with automatic imports from the weather station software into a SQL Server database every two minutes and five minutes. Two minute data is stored for one day, however five minute readings are kept for historical reporting and are automatically imported to the main database just after midnight. Data is captured from the weather station using 'Virtual Weather Station' software and this software is used to save data into a simple text (CSV) file. This data is then imported into the seperate database using SSIS packages and TSQL scripts.

The Webcam, satellite receiver and the lightning detector are all connected to a separate "Imaging Server" due to the extensive processing these tasks need. Periodical data imports from various extenal websites are also made by the Imaging Server for the compilation of weather forecats and weather charts. Any charts, images or forecast data are automatically copied to the separate Webserver for publishing to the webiste. A separate webserver has been created due to the amount of hacking attempts we receive from various countries around the world.

All servers are connected to each other by a wired network and all servers and network equipment are powered through their own battery backup UPS. A generator is also available to supply power to all of the servers and network equipment in the event of an extended power failure caused by storms or other extreme weather events.
