Does it have to be wireless? Can you run a 4 wire cable or cat5 to all
the sensors?

If yes then there are quite a few ways, RS485 can be daisy chained to
quite a distance (depending on conditions 4000').
I'm working on a similar project and you can view the Cricket
schematics at www.myblueroom.com

Also for short runs <300' total you could use 2 wire (data & gnd)
iButtons / 1wire devices www.ibutton.com

As for wireless you might google zigbee or zwave thermostats
.
