Ultrasonic Sensor Arduino Interfacing, SONAR Arduino interfacing, how to interface ultrasonic sensor with Arduino, Interfacing ultrasonic sensor with Arduino, Interfacing SONAR with Arduino, SONAR pinout, Ultrasonic sensor pinout, how to interface Arduino with ultrasonic sensorHello everyone! I hope you all will be absolutely fine and having fun. Today, I would like to provide a complete discussion on Ultrasonic Sensor Arduino Interfacing. I would like to tell you some detail about ultrasonic sensor, after that we will move towards ultrasonic sensor Arduino interfacing. Ultrasonic sensor is also known as SONAR sensor. SONAR basically stands for Sound Navigation and Ranging. Ultrasonic is mostly used for the distance measurements. It can also be used for measuring the depth of the sea.

I have already shared Ultrasonic Sensor Library for Proteus. Ultrasonic/SONAR sensor is an electronic device used to estimate the distance of an object by continuously transmitting sound waves at a particular frequency and listens to that transmitted sound wave to bounce back. It measures the time between the transmission and receiving of that sound wave, which is actually equal to the distance of an object from the SONAR. An optical sensor has both a transmitter to transmit and a receiver to receive the waves. But in comparison to that optical sensor ultrasonic sensor has only a single element for both transmitting and receiving ultrasonic/sound waves. I have also shared Ultrasonic Sensor Simulation in Proteus. Ultrasonic sensor has four pins whose detail will be given later in this tutorial. This is another sensor similar to the ultrasonic sensor i.e. PNG sensor. PNG has three pins. Both of these sensors are designed for the estimation of the distance of an object from the sensor. In this tutorial I am going to use ultrasonic sensor. The basic principle of ultrasonic sensor is that, it transmits ultrasonic waves and receives it back after getting reflected back from the surface of the object and measures the time between transmitting and receiving of the ultrasonic wave. The further detail about ultrasonic sensor/SONAR will be given later in this article.

Ultrasonic Sensor Arduino Interfacing

Ultrasonic sensor is also known as SONAR. It is used for measuring the distance between the object and the sensor itself. It transmits ultrasonic waves and receives it back after reflecting from the surface of an object. Then its measures the time during entire process which is equal to the distance between object and the sensor itself. It has four pins and is very easy to use. It is easily available in the market and is available at very low cost. It has a wide range of applications e.g. estimating the sea’s depth and many more. SONAR/ultrasonic sensor along with proper labeling is given in the figure shown below.

4. Ultrasonic Sensor Working Principle
  • Ultrasonic sensor transmits sound waves.
  • These waves are reflected back from the surface of an object.
  • Ultrasonic sensors receives the reflected waves.
  • Then it measures the time elapsed during the entire process, from transmission to receiving, it is known as round trip time.
  • This time is equal to the distance between an object and the sensor itself.
  • I have also provide some visual, so that you can easily understand its working principle.
  • Ultrasonic sensor principle is shown in the figure given below.
