1) 利用 Arduino 的数字引脚给超声波传感器的 Trig 引脚至少 10 微秒的高电平信号,这会让HC-SR04 超声波测距模块发射出8个40K赫兹的超声波脉冲(ultrasonic burst)。 2) 8个超声波脉冲发出后,echo引脚会输出高电平。假如没有声波返回,echo引脚会在38微秒后输出低电平。假如有声波返回,echo引脚会进入低电平状态。

In this tutorial, you will learn how the sensor works and how you can use it with an Arduino. I have included 3 examples with wiring diagrams that show the basic operation of the sensor. We will look at the different outputs of the sensor and how you can trigger the sensor with a pus...
I have included 5 examples with a wiring diagram and code so you can start experimenting with your sensor. We will first look at an example that does not use an Arduino library. Next, I will show you how you can use theNewPinglibrary to create a more compact code. ...
The experimental data are collected with the help of an HC-SR04 ultrasonic distance sensor and an Arduino Uno board. The data are then graphed and analysed using Microsoft Excel in real-time. The experiment data can be used to investigate Hooke's law. The elastic constant of the spring, k...
