This project demonstrates how to use an HC-SR04 ultrasonic sensor with Arduino and ESP32 to measure distances accurately and integrate them into DIY electronics or IoT projects. The ultrasonic sensor ...

This project focuses on developing a radar system utilizing an ultrasonic sensor and Arduino to detect objects and measure real-time distances, enabling effective obstacle avoidance.

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

Infrared certainly has its uses, but if you’re trying to locate objects, ultrasonic detection is far superior. It’s contact-less, undetectable to the human ear, and it isn’t affected by smoke, dust, ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

Abstract: The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the ...

Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor ...
