Our station uses ten sensors, all hooked up via a 1-wire or “daisy chain” network. They measure wind speed and direction, temperature, daylight and relative humidity. An electronic rain gauge records rainfall and a lightning sensor detects lightning strikes up to 50 kilometers away.
Not spending large amounts of money while still achieving accurate results have been a major part of the challenge and the fun. Many of the components in the system are mounted in basic household items; the webcam in a torch, the lightning sensor an electrical junction box and conduit and the temp/humidity sensors are screened from the sun and rain by 7 Chinese noodle dishes.
Along with the sensors mounted outside on the TV mast, a digital barometer and an additional temperature sensor to measure indoor temperature are patched into the LAN inside our house. Weather Display software reads and computes every few seconds and uploads weather data and graphics to the Milsons Passage website every 15 minutes via a Toshiba laptop computer. The webcam operates via Cam Wizard software and updates ever couple of minutes. We use the Log Me In to can be remotely rebooted or adjust the programs on the laptop.
As unique as it might sound, there are thousands of communities around the world who similarly boast and rely on their own “Ham” amateur weather stations. Why not visit http://wdworldmap.com to check the weather in similar little stations around the world.
