摘要
在当今信息化时代,各种信息的感知、采集、转换、传输和处理的功能器件——传感器,已经被应用到各个应用领域。对于普通的传感器而言,它在功能上有很多局限性,如数据采集系统处理数率较低、数据传输量少、可靠性与稳定性低、低的分辨率与低信噪比。而无线智能传感器带有微处理机,具有采集、处理、交换信息的能力,是传感器集成化与微处理机相结合的产物。
本设计采用Zigbee技术对无线传感器模块进行了自组网,在成熟的温湿度传感器的基础上,完成了各个无线传感器节点以及与主节点之间的相互通信,提出了无线传感器网络的解决方案。设计中采用Zigbee无线模块为传感器的应用和维护提供便利条件。各个节点采用电池供电,使传感器的体积变小,应用起来更加小巧灵活。根据ZigBee/,把低功耗、低成本作为主要目标,可在数千个微小的传感器之间实现相互协调通信,而采用Zigbee芯片内部集成的低功耗增强型8051微控制器,使对传感器的通信和控制变的更加灵活。

ABSTRACT
In today's information age, information perception, acquisition, conversion, transmission and processing of functional devices -- sensor, has been applied to various fields of application. For ordinary sensors, its function has many limitations, such as data acquisition system treatment rate is low, the volume of data transmission, reliability and stability is low, low resolution and low signal to noise intelligent sensor with microprocessor, with the collection, processing, the ability to exchange information, is integrated sensors and bination.
This design uses the Zigbee technology on wireless sensor module to the ad work, in the maturation of the temperature and humidity sensor based on, completed each wireless sensor node and munication between the master node is proposed for wireless work using Zigbee wireless module for sensor applications and maintenance of node uses a battery to supply power, so that the sensor is smaller, pact and flexible to the ZigBee/ protocol standard, low power, low cost as the mai
