Zigbee Modul

Advantages of Zigbee low power consumption. At the low power consumption standby mode, two No.5 dry-charged batteries can support one node to work 6 24 months, or even longer. low cost. Because of dramatically simplifying the protocol, Zigbee reduces the requirements for the communications controller. Zigbee is protocol patent fee free. low rate. Zigbee can work at the low rate of 20 250 kbps. short range. Transmission range is generally between 10 100 m (32.8feet 328 feet). short time delay. The response speed of Zigbee is very fast, in general, it merely need 15ms from the into work state and it merely need 30 ms from nodes connect into the network state.. high capacity. Zigbee can adopt star topology, platy and mesh network structure, composing of up to 65,000 network node. high security. Zigbee provides a three-tier security model, including the use of Worry-Free Security settings, the access control list (ACL) to prevent illegally accessing the data and Advanced Encryption Standard (AES 128) symmetry password. license-free frequency band. Zigbee adopts direct sequence spread spectrum of the industrial scientific medical (ISM) band. 2. 4 GHz (global), 915 MHz (USA) and 868 MHz (Europe) The Applications of Zigbee Wireless Sensor Network( WSN) wireless automatic meter reading system of water, gas, heat, electricity meters wireless intellectual traffic control, signal lights control and street lights control wireless fire safety alarm, building monitoring wireless catering order, canteens sale of food system wireless Access Control, Time and Attendance System wireless PTZ monitoring, engine room equipment monitoring wireless Store & Logistics, laser guns, bar code reader wireless RFID remote data transmission wireless meeting ballot system wireless mapping instrumentation data acquisition wireless POS Terminal wireless electronic bus stop board wireless Queuing System wireless OCS-A ,electronic weighing instrument wireless car inspection and four wheels fixes position wireless parking lot charge system wireless medical monitoring system wireless driving test monitoring system wireless water conservancy and hydrological monitoring system wireless agriculture irrigation monitoring system Technical information Environment of UseIndustry Standard Maximum Transmission DistanceInternodes Barrier Free: 100 meters(328feet)Wireless Frequency2.4G ISM License-free Frequency BandChannel Mode16 Channels Can Be Specified or the Best Channel Can Be Automatically SelectedAntenna ConfigurationBuilt-in 2.4G Ceramics AntennaNetwork StructureStar Topology Network, Cluster Tree Network, Chain Network , Mesh NetworkNetwork ID255 Network ID Can Be SpecifiedNode TypeCenter Node, Routing Node, Terminal Node, Jumper Wire Set or Software SetSerial Rate1200-115200Send ModeBroadcast Send or Destination Address SendWorking VoltageDC-3VPeak Current40mA
