I've had nRF24L01+ow power modules transmitting about 30ft through a couple of walls and a floor. In open space I think they'd work fine.

For about £1.30 each from China, it's certainly affordable to get yourself a few and give them a go with the Maniacbig libraries. RF24Network was designed as a sensor network so should do exactly what you have in price.

If you do need longer range then the high power version of nRF24L01+ is available for about £7.50. I've had them doing about 150m through a window and down a street in an urban environment. If you can get height to clear the Fresnel Zone better then I'm sure you could increase that.

With RF24Network you can insert repeater nodes to extend range, in a similar topology to XBee but at a fraction of the price.

Thanks, sounds like these nRF24L01+ may also be an option. I have had a quick read up on them Nd I love the price. If I wanted my arduino board to read 4 analogue inputs, would I need 5 or 8 of the nRF24L01+ boards?

Each Arduino would need one nRF24L01+.

I've received my nRF24L01 boards. I see there are few libary's out there for this board. What's the generally feeling on which one is the best?

Whats not clear to me is how do you set the address of each nRF24L01 so they know who to talk to?
