摘　　要：随着传感器技术的不断发展,如何更好地对信号进行处理越来越重要。利用霍尔传感器产生的电压作为输入信号,经单片机采集并进行A/D转换和串行通信后,最终在PC机上显示出来。该系统采用的软硬件实现方法,操作过程简单方便,得到结果与示波器上显示的曲线相符,具有重要的参考价值。With the continuous development of sensor technology, how to process signal becomes more and more important. A system whose voltage signal is generating from hall sensor, realizing A/D conversion and serial communication by microcontroller,and it can display comparative results on the computer at last. This software and hardware implementation method used in the system is simple and convenient, the showing result is identical with the curve displaying on the oscillograph. The method has important reference value.
