I am new to the arduino world.
My project consists of collecting temperature data from various points of my house with LM35 sensors and XBee's. I want to collect the to a single point and transmit data to a service like pachube.
Please confirm that the h/w that i need is:
for each point I measure temperature
1 xbee 2.5 1 SparkFun - XBee Shield
for the central point
1 arduino 1 xbee 2.5 1 arduino xbee shield 1 ethernet shield
1 xbee explorer USB for programming xbees
is this correct?
