摘　　要：设计了以无线收发模块nRF401为核心,采用超低功耗MSP430系列单片机,结合外围传感器和Flash存储模块的传感器网络节点.MSP430F149控制传感器采集环境中的温度、湿度数据,并对原始数据进行初步处理,再由无线收发模块nRF401将数据发送给相邻节点.数据经传感器网络节点的逐级转发,最终发送回主机,实现对数据的采集.In this paper, a design of wireless sensor network node based on wireless communication module nRF401 is introduced. The node is consist of low power single chip MSP430, sensors and Flash module. MSP430F149 makes sensors to collect the temperature and humidity signals in environment, and processes the original data, and then sends the data to the neighboring nodes by wireless communication module nRF401. The processed data are sent to the host computer finally, and the habitat monitoring is realized.
