介绍通过MSP430单片机在计算机上实现数据采集设计方案。该系统可实现对温度、盐度、压力、浓度等信息的采集,可上传至上位机,通过人机界面进行交互显示、数据分析。系统采样功耗低,精度高,操作方便。并给出以MSP430F149为核心的硬件电路图和主要的源程序。经过实践证明,此系统对浓度等信息采集精度较高。
Introduced through the MSP430 microcontroller data acquisition on the computer design. The system can achieve the temperature, salinity, pressure, concentration and other information collection, can be uploaded to the host computer, interactive display through the man-machine interface, data analysis. System sampling low power consumption, high precision, easy to operate. And gives the MSP430F149 as the core of the hardware circuit diagram and the main source. After practice, this system of high concentration and other information collection accuracy.
