Phil,

Instead of using low range 2.4GHz,
why not using a rfPIC12F675(F,G,H) for the various ISM frequencies (315, 43=
3, 866 or 915) for your sensors, and one receiver + small PIC (I forgot the=
 part number) for your slave with display.
Microchip sells kits to do just that and they are inexpensive.

Just my $0.02,
Jean-Paul
