Hello,
Thank you for getting in touch.
Examples of projects based on ultrasonic sensors are available in instructables, example: https://www.instructables.com/id/Arduin ... owing-Car/
Another example explained here.

In addition, you can connect your system easily to the AskSensors cloud as shown in this tutorial.

Wow, seems interesting.
As the ultrasonic sensor is being an electronic device that measures the distance of a target object by emitting ultrasonic sound waves, and converts the reflected sound into an electrical signal. it is similar to how the owl find objects right..
