When it comes to measuring distance or detecting an object let’s say in front of your car ultrasonic sensors are widely used in such application so in this Tutorial we will learn how a Ultrasonic Sensor works and how you can use it with the your Arduino so without any further ado Let’s get started! An ultrasonic sensor is an electronic device that is used to measure the distance of a target by emitting ultrasonic sound waves and it converts the reflected sound into an electrical signal. Ultrasonic waves produced by this sensor have frequency of 40KHz, and we humans can only sound in the range of 20-20KHz hence it’s not audible. To understand it better Ultrasonic sensors have two main components The transmitter and receiver, as you can observer this ultrasonic sensor has two cylinders which are nothing but our Ultrasonic transmitter and the receiver. If I point the sensor toward an objec
