One of Popular Wireless Module

Xbee is one of popular wireless module in the world. It support two-ways communication (one Xbee module can send or receive the data to/from other modules).The different between Zigbee and Xbee is Zigbee is name of industry standard while Xbee is name of Zigbee standard module produced by Digi.

Xbee can communicate via UART (TX,RX signal) and sending the signal (data) within the short range is very accurate.Xbee module have an internal IC that help in encoding the data.The main advantage of this module is it consume low watt (low electric power),small size and cheap.Although it is restricted to send data within short distance, it can send data from one node to another node and this feature make it appropriate for making wireless sensor network.
