Based on APMS-10G turbidity sensor, the data is acquired and exchanged with computer by the serial communication method,the digital filter is finished by software,the signals are processed and analyzed by Matlab signal processing tools.

• 主要方法是使用浑浊度传感器进行数据采集,采用串行通信方式实现计算机与传感器之间的数据交换,利用软件完成数据的数字滤波,运用Matlab中的信号处理工具对采集信号进行处理与分析。
