摘　　要：本文主要介绍了基于MSP430单片机的智能气象站的设计思路,硬件上采用模块化设计方法,便于增加新的检测任务。模块间采用SPI总线通信。系统能够对多通道的温度、湿度及大气压数据进行通道选择、数据采集、数据处理、液晶显示,同时还设计了基于USB(Universal Serial Bus)技术的数据存储系统,改善了数据传输速率和存储容量。the scheme of the automatic weather station design based on MSP430 single chip is presented. Modularization is used in hardware design so that new nodes or new checking tasks are added conveniently. These modules communicate with each other through SPI bus. The channel selection, data collection, data processing and LCD display of temperature, humidity and air pressure will be introduced. Furthermore, the data storage system based on USB is also designed, which improve the speed of data transmission and storage capacity.
