下面这个实验就是用ultrasonic sensor这个传感器来测量距离的,整个电路的连接非常简单,就是用一块超声波传感器去控制一块LCD的屏幕,如图所示,超声波传感器能感受到与前面障碍物之间的距离,这个距离会实时显示到LCD的屏幕上。超声波传感器上会有4个需要连线的脚,GND就是用杜邦线接电源接块的负极,VCC就是去接电源接块...
How to Filter Noise from Distance Measurements of Ultrasonic Sensor 如何过滤超声波传感器距离测量的噪声 The measurement result from ultrasonic sensor contains noise. In some application, the noised result causes the unwanted operation. We can remove noise by using the following algorithm: 超声波传感器的...
