ZigBee Wireless Interfaces and Modules

ZigBee wireless is the ideal solution for creating flexible and robust networks for control and monitoring applications. Kanda sell a range of Sena ZigBee products that make it easy to create a wireless network from scratch or with ZigBee sensors from other manufacturers.

What is a ZigBee Wireless Network?

Zigbee network Diagram

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 connection. 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
  • Long range

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 network. Most users use a ZigBee USB dongle as the Coordinator and either ZigBee serial adapters or embedded modules as routers or end points but all can easily be configured by you to be different types.

Any ZigBee product from other manufacturers can be used with these Sena units providing they conform to IEEE 802.15.4 standard. This means that a ZU-10 USB to ZigBee adapter can be used as a network coordinator for a huge range of sensors and control units and provide a PC interface at the same time.

Instant ZigBee Network Control

The ZU10 series are USB to ZigBee products 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 other units forming the rest of the network. These can be
  • ZS10 ZigBee serial adapters for wireless enabling units with serial ports
  • ZE10 embedded modules for creating your own ZigBee sensors or control unit
  • ZigBee sensors and units from other manufacturers

ZS10 serial adapters can also be set as a network coordinator if that suits your requirements better. All Sena units come with easy to use control and setup software to create your network.

The combination of these two ZigBee products gives you a ZigBee network with ranges up to 1.5KM. You do not need to understand ZigBee or wireless and you don't need to modify your existing equipment. With setup and management via Windows Management Software, Telnet or a Terminal Program, you have all the flexibility you need.

Embedded ZigBee to Serial Modules

Sena embedded ZigBee modules are the best products on the market. They have built-in RS232, ADC and General I/O interfaces. This means you can use them to create a wide range of ZigBee enabled sensors and controllers. They are supplied with an on-board 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.
