ZigBee Wireless Interfaces and Modules
A range of ZigBee wireless adapters and embedded modules that simply convert existing serial ports to wireless, or let you create a whole new ZigBee network, with ADC or Digital I/O. The range includes long range USB to ZigBee adapters and RS232 ZigBee adapters to convert existing serial port products to ZigBee wireless, with optional antennas to give up to 1.5Km range.
What is a ZigBee Wireless Network?
ZigBee networks can be cluster, star or mesh networks as shown in the diagram. Each ZigBee network has one device that is setup as a coordinator that controls and initialises the network. Other devices can either be setup as routers that can pass data or as End Points, that can only have one connections. End points or Reduced Function Devices can be set to sleep mode so they use very little power and so can be battery operated.
Because of this very low power requirement, ZigBee is ideal for sensor networks or other control applications, which require:
- Low to medium data rates
- Lots of nodes (up to 65,565)
- Easy addition or removal of nodes from network
- robust mesh network that doesn't fall over if one node fails
- very low power, battery operated equipment
The management software that comes with all Sena ZigBee products makes it very easy to setup the coordinator, routers and end points to create the nwetwork.
Instant ZigBee Wireless Adapters
The ZS10 RS232 to Bluetooth Wireless adapters give you an instant ZigBee wireless interface for all your products and equipment. They can be easy configured to give you a wireless network, with a USB adapter to connect with your laptop, your PC or other equipment.
Instant Wireless Network
The ZU10 series are USB to ZigBee wireless adapters that can create a wireless network linked to a PC. They are extremely flexible and can be set up very easily to be the ZigBee network coordinator with ZigBee serial adapters forming the nodes in the network.
Embedded ZigBee to Serial Modules
Embedded ZigBee modules that are the best on the market, to fit in your application, with RS232, ADC and General I/O interfaces. These modules are supplied with chip antenna or with external antenna connectors. Alternative antennas are available to give up to 1.5Km range.
A Starter kit is available to get you going with the modules.
