摘　　要：以Microchip的PIC24FJ128GC006作为中央处理单元,以LabVIEW为上位机软件开发平台,研制一套DHT8X型数字式温湿度传感器的数据采集系统,由单片机对多路数字信号进行数据采集,通过RS232将采集的数据传输到上位机,由LabVIEW设计的数据采集系统进行数据显示、处理、存储,并生成数据记录。经验证,该套装置操作简单,数据读取准确,运行性能良好。In this paper, Microchip’s PIC24FJ128GC006 is used as the central processing unit, and LabVIEW is used as the host computer software development platform to develop a DHT8X digital temperature and humidity sensor data acquisition system. The multi-channel digital signal is collected by the single-chip microcomputer, and the collected data is transmitted to the upper computer through RS232. The data acquisition system designed by LabVIEW performs data display, processing, storage, and generates data records. It has been verified that the device is easy to operate, accurate in data reading and has good running performance.
