Clearly saving battery power means getting the XBee radio to sleep at the behest of the Arduino. This turns out to be fairly simple, but does require modifying the XBee shield slightly.
Controlling the XBee requires issuing AT commands. The XBee library has the low-level machinery to do this.
Some initial measurements of power consumption.
A simple radio survey establishes the ranges that the radios can manage.
Probably the definitive hobbyist’s description for small-scale sensor networks.
A small sensor network now working, with two edge devices talking to a base station.
A library for using XBee radios with Arduinos.
Managing Digi’s XBee radio modules requires using their X-CTU package to upload the correct firmware. In this post we explain how.
The XBee is a series of small radio modules that implement the Zigbee protocol and work well with Arduinos.
