Re: [PLUG] (possibly OT) weather tracking 

Thanks for the comments everyone. It's given me options to consider.

I have one of these:

Which are on sale for $100, so might be doable.


tied to a raspberry pi running wviewweather (wviewweather.com
Is that so you don't have to connect to a PC every so often (can't find how long the WS keeps it's history for)? 

How difficult was it to mount?
It's only the one spacial point though, and I don't see any way to add additional sensors without buying whole separate kits - then I end up with multiple base stations to pull the data from.

    Raspberry pi + arduino + temp/humidity sensors + lots of cat cabling
    ($0.xx) or multiple wifi modules ($xx.xx)

    Conjuring up a windspeed/direction sensor sounds like a lot of fun, too.


Plus making sure everything stays water-proof...
When I said "a bit of mucking around" I was thinking software getting data into sensible formats, pretty graphs, etc. (though it looks like wviewweather does almost all that).
I've discovered the hard way that I'm much more software than hardware. I can do some hardware stuff, but the time, cost and frustration is rarely worth it to me.

        The build however is based on using cubesensors
        <http://www.visionect.com/blog/raspberry-pi-e-paper/>.  Not
        $1000's but a 4 unit system + base station is $450.  Each cube
The cubesensors look really interesting, cost is a bit high though and they are clearly indoor-only use, so doesn't satisfy the original goal.
If you could get waterproof ones for around $20 each, that would be perfect... 


        sends data over ZigBee to the base station but the thing that is
        not clear is if the base station needs to be connected to the
        internet all the time (I suspect the answer to that might be yes
        because of this obsession with running everything as a remote
        service).
from what I could tell, they do want to have a network connection, but they do a cell-network and you might be able to hack one of the cubes to get the data out without sending it upstream. expensive to find out though. 


        You could also use DYI this with a Raspberry Pi, Beaglebone
        Black or even an Arduino with the exact sensors you want (see
        http://www.adafruit.com/categories/35 for example).  There lots
        of code examples around for these types of projects so you
        should be able to do a build cheaply and only have a minimum of
        mucking about.
