Tiny Talking Modules: An Introduction to XBee Wireless Modules

The application of sensor networks often precludes the use of wired sensors. Although it’s possible to use wired sensors installed in a controlled environment that supports a cable plant, you seldom have this luxury. Sometimes you can connect some parts of a sensor network to a wired network, but the sensors are located in areas where running wires is impractical. Thus, most sensor networks require using wireless technology to transmit data from the sensors to other nodes in the network.

There are many forms of wireless communication. This book uses one of the easiest: the ...
