I want to create a growhouse sensor system. I have an Arduino UNO, wireless SD shield and I have just ordered a series 2 XBee XB24.
Any info I find seems to revolve around having 2 Arduinos and 2 XBee modules, why is that?
I am presuming that once I connect the XBee to the shield that I can then connect to my Arduino on the network and send and receive data, am I wrong?
I'm a developer and sysadmin but a noob to Arduino so any help is much appreciated.
