Hello all..
first things first, Im an absolute novice trying to provide guidance on a project.
the details are for
- wireless outdoor network, a golf course - so some trees/clear LOS path
- approx 20 nodes, ie node per hole
- some nodes would just be repeaters
- some nodes would be sensor equipped (ie prox card or swipe card) and a display; or maybe bluetooth equipped (
The term to look for is 'sensor networks'. There is an enormous variety to choose from.
For low datarates/low power Zigbee may be more suitable than Bluetooth.

Fixed number of nodes. Low data rate. Why go wireless? Run wire.
If you're clever, eliminate the batteries by making the nodes line powered too.

I've been told that drilling rigs communicate with their down-hole instruments by modulating the mud/slurry that they pump down to lubricate the drill bit. Something like a 1Hz modulation on the gunk.
I wonder if you could communicate with the sprinkler heads by modulating the pressure of water in the pipe? If you put a wee tiny waterwheel on each sprinkler, you might leave out the batteries and power line ;)
