What is an Ultrasonic Sensor?
Similar to any other sensor, the Arduino Ultrasonic Sensor is used to sense the presence of any object and predict the distance of the object in appropriate units which is inches in this case. Therefore, we can define the Arduino Ultrasonic Sensor as a device that uses the ultrasonic sensing technique to estimate the distance of an object.
Arduino is used for creating this sensor since it needs to be programmed to detect the reflected rays from objects and display the distance in the desired format.
Arduino – Ultrasonic Sensor
Sensors are widely used for detecting devices by approximating their distance from the source. One such example of a sensor is the HC-SR04 ultrasonic sensor which uses the SONAR technique for the sensing purpose. The main feature of this sensor is to mimic the nature of bats and therefore predict the distance of objects without actually establishing contact with the device.
In this article, we will study how to design this ultrasonic sensor using the Arduino board and programming software. We will study the specifications needed for this sensor, and the methods and circuit diagrams used for designing this sensor. In addition to this, we will see the Arduino code written on IDE that will result in a sensor.
