基于ZigBee的无线温湿度传感器网络设计与实现

Design and Implementation of Wireless Temperature and Humidity Sensor Network Based on ZigBee Technology

在生产和科学研究过程中的很多场合对环境的温湿度有较高的要求。为了更方便快捷的监控环境温湿度,文中针对有线温湿度监测系统布线复杂、成本偏高以及后期维护不便的问题,结合无线传感器网络技术,设计和实现了一种基于ZigBee技术的温湿度监测系统。本方案采用星状网络结构,采用集成了51内核的无线射频芯片CC2430以及高集成度的数字温湿度传感器SHT11构建节点硬件,并实现了节点软件。测试结果表明,本系统具有低功耗、低成本、易于维护扩展等优点。

There are several requirements for the environmental temperature and humidity during production and scientific research proces- ses. To conveniently and quickly monitor the environmental temperature and humidity and focus on the drawbacks of the wire temperature and humidity detection system, such as complicated layout,high cost and discommodious maintenance,it designed and realized a tempera- ture and humidity joint testing system based on ZigBee and wireless sensor network technology. The asteroidal network topology is adopt- ed, and the node hardware is built by using highly integrated SHT111 and the wireless RF chip CC2430 integrated with 51 MCU core. Al- so the node software is implemented. The experimental result implies that the system has some advantages as low energy consumption, low cost and convenient for maintenance and extension.
