Ultrasonic Sensor measure the distance of target objects or materials through the air using "non-contact" technology. They measure distance without damage and are easy to use. The output Signals received by the sensor are in the analog form, and output is digitally formatted and processed by ...
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 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...
