I've come by one of these recently, and have been playing with 
it for the last month or so. It's intended as a remote 
transmitter for a central weather station, but works fine 
without the receiver. It seems to be pretty accurate, though I 
can't verify the extremes of it's range, even though the 
listed specifications are on the high side of optimistic. It's 
an "always on" thing, and on the large side, but the price is 
right.

FWIW.
