[lug] (Sort of OT) Serial Thermometer

[Landon Cox]

I'm sure you saw this since you said you checked with SparkFun, but  
maybe it's overkill for you since it's more than just temperature:

I connected it serially (TTL) to an XBee and do XBee<->XBee comm with  
a Linux box.   It works either way, USB or TTL serial.   It's insalled  
outside so I embedded it in a Hammond enclosure with the lid facing  
down and made holes in the lid with a screen to keep bugs out and let  
ambient air in.   It's solar powered also.  There are some pictures of  
it here:

I've been using this board to export temperature data to CWOP for a  
long time:

The wind data in that CWOP link is coming from another micro with  
firmware I wrote...an open source project called OSCirrus:

but the temp and humidity is coming from the Sparkfun board.
