摘要
为提高磁感应强度采集与显示的有效性,设计了一种基于C8051F350单片机与SS495A霍尔传感器的信号采集与显示系统.通过霍尔传感器把磁场强度转化为电压并作为输入信号,经放大器AD620进行放大后输送到单片机中采集并由其自带模/数转换器进行模/数转换,最终在显示屏上显示出来.实验结果表明,霍尔电压能够很精确测量出来,显示屏上显示的霍尔电压与记录的数据相符合,验证了方案的可行性,实验设计达到了预期目标.
In order to improve the effectiveness of acquisition and display of magnetic flux density, a scheme based on C8051F350 microcontroller and SS495A hall sensor was designed . The input signal was voltage which was transported by magnetic field strength through hall sensor; the voltage signal was amplified by the amplifier AD620, and transported into the microcontroller; analog to digital （A/D） conversion processing was accomplished by the microcontroller itself; the data finally displayed on the liquid crystal display （LCD）. Experiment results show that hall voltage is measured accurately which is consistent with the recorded data, the feasibility of the scheme is verified and the design goal is reached.
