We know everything produces sound wave just by existence and effect flow of air around them with their natural frequency. These frequencies are beyond hearing range of humans. Wave of frequency range ...

Visualizing the environment with an ultrasonic sensor by gathering points that form a 3D point cloud using Arduino. This project aims to visualize real-time data from an ultrasonic sensor mounted on ...

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 collaboration of ...

Abstract: This study focuses on the development of an obstacle avoidance robot controlled by an ultrasonic sensor. The robot utilizes robotics and artificial intelligence techniques to improve ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...
