Weather data:
Data is collected every two seconds 24 hours a day, 7 days a week. This data is beamed wirelessly from the station hardware mounted outside to a console located inside which stores this information. When the computer is switched on, the data is downloaded from the console using Lightsoft Weather Center software. This software analyses the data, converts it to spreadsheet format, generates forecasts and publishes information on the internet via FTP.
Webcam:
This webcam (a Logitech Pro 9000) points in a northerly direction from my office window with imagery automatically uploaded every 15 minutes using EvoCam when my computer is on. To be honest, it's a bit of a boring view but you can often see trains going by in the foreground (Plymouth to Paddington mainline) and the camera often catches impressive sunsets and cloud formations building over Dartmoor.
The weather station
I am using a wireless Davis VP2 as the main station hardware. This is mounted outside on a wooden pole. Scientifically speaking, it is not a very good site for a weather station as there are numerous trees and buildings within close proximately. So wind readings are not very accurate all the time. But living where I do, this is the best possible site to mount the hardware.
The weather website
Lightsoft Weather Center publishes data and graphs to a standard web server. I have then developed various plugins and scripts for Stacks (a RapidWeaver plugin) to fetch the data and present them on this site. Used on the weather page are webcam, URL image, spacer and PHP get-content content stacks.
