ZigBee is a specification based on the IEEE 802.15.4 standard for wireless personal area networks (WPANs). ZigBee operates in the ISM radio bands, and it defines a general-purpose, inexpensive, self-organising, mesh network for industrial control, embedded sensing, medical data collection, smoke and intruder warning, building automation and home automation.
There are three different types of ZigBee devices in a ZigBee network:
- Coordinator (Master): Only one coordinator exists in each ZigBee network. Its function is to store information about the network and to determine the optimum transmission path between any two points of the network.
- Full function device (Router, Repeater): Routers act as an intermediate repeater that passes data from other devices.
- Reduced Function Device (End Device): This device contains a minimal amount of functionality to enable it to talk to its parent node (either the coordinator or a router); it cannot relay data directly from other devices.
The family of product includes Analog I/O, Temperature sensors, Digital I/O, Multifunction I/O, Zigbee Sniffers, Repeaters and Converters (RS232/485, Ethernet and USB to ZigBee). All models feature -25C to +75C operation, ESD/EFT protection, 10-30VDC wide range power supply, dual watchdog timer, Windows GUI Configuration Software, and are DIN Rail mountable.
