I like MaxStream's XBee for sensors like this.  Longer typical range 
than Bluetooth, and lower power because it's meant for frequent 
connect/disconnect, while Bluetooth likes to be always on - or at least 
those are the arguments I've heard, I haven't worked with Bluetooth.

Modules are what, $22 or $32 depending on which power level you want. 
Dead easy to set up - in fact, you might not need an external 
microcontroller at all for the application you're describing.
