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
How To Program For Ultrasonic Sensor 如何对超声波传感器进行编程 Generate a 10-microsecond pulse in Arduino’s pin by usingdigitalWrite()anddelayMicroseconds()functions. For example, pin 9: 使用digitalWrite() 和 delayMicroseconds() 函数在 Arduino 的引脚中生成 10 微秒的脉冲。例如,引脚 9: digitalWrite...
The MB1240 XL-MaxSonar-EZ4 is a high-performance ultrasonic distance sensor with a range of 20 to 765 cm. While this tutorial is written for the MB1240, it can also be used for other MaxBotix sensors, and serves as a great reference for those interested in using an ultrasonic sensor with...
Next up we have our very own Grove – Ultrasonic Distance Sensor, Seeed’s very own version of an ultrasonic distance sensor which is comparative to the HC-SR04. It can measure from 3cm to 350cm with the accuracy up to 2mm. It is a perfect ultrasonic module for distance measurement, prox...
