![]() This circuit can also be called an object detection circuit. Ultrasonic Sensor Without Arduino circuit diagram: Output at echo pin is a rectangle wave with a variable duty cycle. Depending upon the distance of the object from ultrasonic sensor output at the Echo pin changes. Add Trigger pin we give a high-frequency square wave. HC-04 module has 4 pins namely Vcc, ground, Trigger, and Echo. ![]() Ultrasonic waves are also used by bats for navigation. So it can send as well as receive ultrasonic waves. It has both ultrasonic sender and receiver built on the same module. It is a module you can buy from the market in one or two dollars. These are the beyond 20k Hertz frequencies. Ultrasonic frequencies are those frequencies to which we humans cannot listen. How ultrasonic sensors work?Īs the name suggests an ultrasonic sensor works on ultrasonic frequencies. We will interface ultrasonic sensor with a 555 timer to control a DC motor. Hey folks, have you used an ultrasonic sensor in your projects! Do you know how it works? In this project, we will use an ultrasonic sensor without Arduino for object detection.
