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。
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...
Arduino Ultrasonic Sensor I have just received a very affordable fun toy from China AliExpress Market Place, the ultrasonic sensor, it is about RMB15 (USD2.50) excluding the shipping cost or you can get this Ultrasonic Sensor for a very good price from Amazon. … Continue reading → Posted ...
This research work is designed as the distance measurement with energy conservation system using Ultrasonic sensor and Arduino NANO. Ultrasonic sensor emits high frequency sound waves, which reflects from target surfaces. This work utilized these sound waves through Ultrasonic sensor HC-SR04 to determine...
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...
