Do you have a better, cheap & more efficient idea ? remember i will need to use Virtual wire in these nodes and will need to program each node to have its own unique ID using EEPROM.
I like the JeeNodes but they use the RFM12B transcievers which are more expensive ~$5-$8. You can get the nRF24L01 transcievers for ~$1-$2 off of ebay, and with the rf24 library they seem to work really well. The big question is what frequency you want to use 915MHz or 2.4GHz.
I can see It needs 8 wires to be connected to Arduino. but i guess being a member in this lovely community will help me much to figure it out.
