它综合了传感器技术、嵌入式处理技术、无线通信及网络技术、分布式处理技术等多领域、多学科研究成果，其具有类型众多的传感器，可探测包括温度、湿度、噪声、亮度、压力、物体移动速度和方向等各种各样的物理现象，在工业监控、农业、医疗卫生、智能家居等领域都有着广阔的应用前景。

Zigbee是目前应用最为广泛的新技术ew Technology N56无线传感网络协议，是由Zigbee 联盟在IEEE802.15.4标准上定义了网络层、安全层及应用层等，于2004年12月正式获得批准,具有低功耗、低成本、大容量、短时延、协议简单和安全性高等优点，无线传感网采用Zigbee技术具有良好的通用性和可扩展性。

IEEE802.15.4标准中有关物理层部分规定了两个工作频段，分别位于2.4GHz、868/915MHz频段。

其中2.4GHz频段为全球统一的无需申请的ISM频段，有助于ZigBee设备推广和降低生产成本。

2.4GHz频段物理层采用直接序列扩频技术的(DSSS)O-QPSK 调制方式能提供最高250kb/s的传输速率，能够满足一般传感器节点的通信需求。

Zigbee技术资料搜集整理一、Zigbee技术1、简介在蓝牙技术的使用过程中，人们发现蓝牙技术尽管有许多优点，但仍存在许多缺陷。

对工业，家庭自动化控制和遥测遥控领域而言，蓝牙技术显得太复杂，功耗大，距离近，组网规模太小等，……而工业自动化对无线通信的需求越来越强烈。

正因此，经过人们长期努力，Zigbee协议在2003年中通过后，于2004正式问世了。

ZigBee技术是一种应用于短距离范围内，低传输数据速率下的各种电子设备之间的无线通信技术。

ZigBee名字来源于蜂群使用的赖以生存和发展的通信方式，蜜蜂通过跳ZigZag形状的舞蹈来通知发现的新食物源的位置、距离和方向等信息，以此作为新一代无线通讯技术的名称。

ZigBee过去又称为“HomeRF Lite”、“RF-EasyLink”或“FireFly”无线电技术，目前统一称为Zigbee技术。

2、ZigBee是什么ZigBee是一个由可多到65000个无线数传模块组成的一个无线数传网络平台，十分类似现有的移动通信的CDMA网或GSM网，每一个ZigBee网络数传模块类似移动网络的一个基站，在整个网络范围内，它们之间可以进行相互通信；每个网络节点间的距离可以从标准的75米，到扩展后的几百米，甚至几公里；另外整个ZigBee网络还可以与现有的其它的各种网络连接。

例如，你可以通过互联网在北京监控云南某地的一个ZigBee控制网络。

不同的是，ZigBee网络主要是为自动化控制数据传输而建立，而移动通信网主要是为语音通信而建立；每个移动基站价值一般都在百万元人民币以上，而每个ZigBee"基站"却不到1000元人民币；每个ZigBee 网络节点不仅本身可以与监控对对象，例如传感器连接直接进行数据采集和监控，它还可以自动中转别的网络节点传过来的数据资料；除此之外，每一个ZigBee网络节点（FFD）还可在自己信号覆盖的范围内，和多个不承担网络信息中转任务的孤立的子节点（RFD）无线连接。

Product DevelopmentJennic supplies all the development tools and networking stacks needed to enable end product development to occurquickly and efficiently. These are all freely available from Jennic’s support website: /support/ . A range of evaluation/developer kits is also available, allowing products to be quickly breadboarded. Efficient development of software applications is enabled by the provision of a complete, unlimited, software developer kit. Together with the available libraries for the IEEE802.15.4 MAC and the ZigBee network stack, this package provides everything required to develop application code and to trial it with hardware representative of the final module. The modules can be programmed by the user, for both development and production, using Jennic supplied software. They can also be supplied ready loaded with customer defined software if required. The JN-UG-3007 Flash Loader User Guide [5], describes how to put the module into programming mode, download software onto the module and to load individual MAC addresses. Access to the on-chip peripherals, MAC and ZigBee stack software is provided through specific APIs. These are described in the JN-RM-2001 Hardware Peripheral Library Reference Manual [3], JN-RM-2002 Stack Software Reference Manual [4] and JN-RM-2014 ZigBee Application Development API Reference Manual [6]. Additional information is available on the Jennic support website.3.1.

Pin DescriptionsAll pins behave as described in the JN5121 datasheet [2], with the exception of the following:4.3. Power SuppliesA single power supply pin, VDD is provided. Separate analogue (VSSA) and digital (GND) grounds are provided. These should be connected together at the module pins.4.4. SPI Memory ConnectionsSPISWP is a write protect pin for the serial flash memory. This should be held low to inhibit writes to the flash device. SPISSZ is connected to SPI Slave Select 0 on the JN5121. SPISSM is connected to the Slave Select pin on the memory.This configuration allows the flash memory device to be programmed using an external programmer if required. The JN5121 should be held in reset by taking RESETN low. The memory can then be programmed over the UART by using the programming mode described in JN-UG-3007 Flash Loader User Guide [5]. Alternatively, the memory can be programmed by connecting a SPI programmer to SPISSM, SPICLK, and SPIMISO and directly loading the code into the memory.For normal operation of the module, SPISSZ should be connected to SPISSM.Jennic Jennic© Jennic 2006 Preliminary - JN-DS-JN5121-xxx-Myy v1.1 75.

产品概述E75系列ZigBee无线模块是基于NXP JN5168芯片开发的低功耗、高性能型ZigBee模块，它提供一个完整的基于IEEE802.15.4标准ISM（2.4-2.5GHz）频段的应用集成方案。

支持FastZigBee、ZNET、JenNet-IP、ZigBee-PRO、RF4CE等协议，可快速应用于工业控制、工业数据采集、农业控制、矿区人员定位、智能家居，智能遥控器等场合。

E75系列ZigBee模块，将完整的射频收发电路集成在一个模块上，将无线通讯产品复杂的通讯协议内嵌在内置的MCU中，化繁为简，大幅简化开发过程，使得用户产品更快的投入市场，增加用户产品的竞争力，更好的把握住先机。

E75系列为硬件平台，无法独立使用，用户需要进行二次开发。
