一种新型的无线低功耗环境指数传感器

摘要

A design of a wireless environmental index sensor is introduced.MSP430 microcontroller is used as control center,COZIR-W sensor acquire environmental index of site and send it to the microcontroller in the form of digital signal.The data is transmitted out by the X-BEE wireless module after the data is packed.The sensor can act as the node of wireless sensor networks,and communicates with the control center via wireless gateways.A detail description of the design of the main hardware modules and the algorithm for optimizing the path of data acquisition is performed,and a method for realization of low power consumption of the sensor and improvement of the transmission stability is proposed.The results obtained by experiment and test show that it is characterized by low power consumption,good stability,high communication efficiency,and quite suitable for various environmental monitoring.%介绍了一种无线环境指数传感器的设计.该传感器以MSP430单片机为控制核心,COZIR-W传感器采集场所环境指数并将其以数字信号的形式送入单片机,经打包处理后,由X-BEE无线模块向外发送.其可作为无线传感器网络节点,通过无线网关和控制中心通信.详细地描述了其主要硬件模块的设计和优化数据采集路径的算法,提出了实现传感器低功耗与提高其传输稳定性的方法.实验与测试结果表明:该系统具有功耗低、稳定性好、通信效率高的优点,非常适用于各种环境监测中.
