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 ...

A small PlatformIO/Arduino project that measures distance using an ultrasonic sensor (HC-SR04 or similar) and prints the measured distance over the serial port. This README explains how to open the ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

In this IoT-based smart bin project, an Arduino Uno R4 WiFi acts as the central control unit, interfacing with two ultrasonic sensors and a servo motor. The power bank provides 5V via the USB-C port, ...

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 ...

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 ...
