Below you find the tutorials and resources needed to start working with PING))) for both development boards. The PING))) sensor is compatible with an Arduino and Raspberry Pi board. The sensor can detect objects in the range of 3 centimeters to 3 meters. For example, the HC-SR04 uses a separate pin for trigger and echo. PING))) differs from other sensors by using a single pin for trigger and echo.

This tutorial will teach you how to implement the median filter to remove impulse noise from ultrasonic sonar data. Besides the temperature compensation, an impulse noise reduction method can also be applied to ultrasonic sonar data. Taking into consideration the ambient temperature, we can improve the precision of the measurements.
Remove impulse noise from ultrasonic sonar data – The accuracy of the HC-SR04 sensor can be improved. In addition to the ultrasonic sensor, a temperature sensor will also be included. In this tutorial, MagicB圜alvin describes in a few words the physical phenomenon that improves the measurement precision of the distance detected by the sensor. From this tutorial, you will learn how to calculate the distance between the sensor and an object applying the ambient temperature. Improve ultrasonic range sensor accuracy – There is a simple way to improve the accuracy of the sensor. In this tutorial, you will learn the steps required to connect HC-SR04 to the nodeMCU and write the script needed to read the values returned by the sensor. With a more limited capacity than an Arduino or a Raspberry Pi, the ESP8266 nodeMCU is a board that can be connected to the Internet to read the values returned by the ultrasonic sensor. Wiring ESP8266 nodeMCU with HCSR04 Ultrasonic Sensor – For IoT applications, a much cheaper resource than Arduino and Raspberry Pi is the ESP8266 module. Robotc ultrasonic sensor full#
Measure Distance using Ultrasonic Sensor | Pi4J | JAVA | Pi – If you need automation, Java, and IoT, in this tutorial you have an example of how you can access the full I/O capabilities of the Raspberry Pi via Java and read the distance returned by the ultrasonic sensor. In this tutorial, you have an example of how you can return the distance detected by the HC-SR04 sensor using the libraries for Arduino and the Raspberry Pi board. Connecting an Arduino board directly to the Internet is a solution, but depending on the project needs, it is often not the best answer. RPi: HC-SR04 Ultrasonic Sensor mini-project – If you want to build an IoT application, you need an Internet connection. In this tutorial, you will learn how to connect the sensor to Pi and how to use Python to display the distance measured by the sensor. HC-SR04 Ultrasonic Range Sensor on the Raspberry Pi – HC-SR04 can be used with any version of the Raspberry Pi board. With a single line of code, you can read the data returned by the sensor in your preferred measurement unit. Arduino – HC-SR04 ultrasonic distance sensor – From this tutorial, you will learn how to use the “Ultrasonic.h” library to read the data returned by the sensor. This tutorial will teach you how to connect the sensor to Arduino and read the data returned by the sensor. Detection range for HC-SR04 with Arduino and millis() – This is an introductory tutorial that requires an HC-SR04 sensor and an Arduino board. It is by far the most used ultrasonic sensor in robotics and automation projects. The HC-SR04 is an inexpensive sensor that is very easy to use with a microcontroller board such as Arduino or a single-board computer that runs Linux like the Raspberry Pi. We can improve the accuracy of sensing by compensating the environment’s temperature and filtering the sensor’s output. The sensing accuracy of an ultrasonic sensor may be affected by soft materials, the temperature of the environment, and the noise of a wide frequency range. We go further to understand the limitations of a sensor that uses sound waves to detect objects. We saw the advantages of an ultrasonic sensor. In robotics, the ultrasonic sensors are used in applications such as: 
Also, an ultrasonic sensor can be used in a dark environment since the light does not affect an ultrasonic sensor’s detection ability.
We use ultrasonic sensors in robotics when we want to detect obstacles in extreme conditions since the sensor is not affected by dust, moisture, and dirt. This page is still a work in progress and subjected to change in the future! This page was last edited on
