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。
The HC-SR04 is an inexpensive, easy to use ultrasonic distance sensor, with a range of 2cm to 400 cm. It is commonly used in obstacle avoiding robots and automation projects. In this tutorial, you will learn how the sensor works and how to use it with Arduino. I have included 5 exampl...
