Getting started with Ultrasonic Sensor Arduino and Raspberry Pi Pairing Guide For this tutorial, we will be using theGrove Ultrasonic Distance Sensorand pair it with the Arduino and Raspberry Pi. For the first tutorial, we have the guide for Arduino. Scroll down for the tutorial on Raspberry Pi...
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。
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...

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....
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...
This work utilized these sound waves through Ultrasonic sensor HC-SR04 to determine the change in distance and to apply it to detect the presence of an obstacle (person in this case), which in turns triggers a light bulb ON. Sonar waves are projected back to the receiving end of the ...
