For my 30th birthday a group of my friends bought me a [La Crosse
|
|
WS2355][WS2355] weather station. Over the weekend I installed it.
|
|
I mounted the wind speed
|
|
(anemometer) and and direction sensors to the mast of our TV antenna.

The roof of the house seemed like the logical place for the rain gauge since
|
|
there's trees overhead on most of the rest of our block. I bolted the rain
|
|
gauge to a piece of aluminium that Dad had lying the around in his shed. I put
|
|
a slight bend at the end to get the gauge level. I then pop-riveted the bracket
|
|
to the roof.

The thermomometer/hygrometer under the eave of the house, near the TV
|
|
antenna. I bundled up the metres of extra cable between the
|
|
thermomometer/hygrometer and the other two sensors with left over cable ties.
|
|
The bundles hang on a cheap hook that I had in the shed. The end result is
|
|
relatively tidy and tucked away from the elements.

I opted to have the sensors talk to the display via the 433Mhz wireless
|
|
connection to save having to run wires in through the wall or roof. The
|
|
downside of this is readings every ~130 seconds instead of every 8 seconds.
|
|
This is mainly an issue for the wind speed/direction but the temperature is
|
|
what I'm most interested in.

To log and upload the [weather readings][weather] I'm using the [wview][wview]
|
|
weather station software. wview is running on the Mac mini connected to our TV.
|
|
The site layout is pretty basic so I hope to come up with a cleaner design in
|
|
the coming weeks.
|
|
|
|
**Update:** I built a custom logging and charting solution. See the post,
|
|
[Weather Station Software][software].
