This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

Project Overview: This project involves creating a functional radar system using an ultrasonic sensor, Arduino Uno, and a breadboard. The radar is capable of detecting objects within a specified range ...

Abstract: Based on Mach-Zehnder interference (MZI) principle, we propose a balloon-like optical fiber micro-liquid-level sensor and verify its performance through experiments. The sensor can ...

Ultrasonic energy is widely used to sense the presence of nearby objects and even determine their distance if needed, as well as to measure fluid flow rates in industrial and scientific applications.

Abstract: This article presents a novel liquid level monitoring system based on passive ultrahigh-frequency (UHF) radio frequency identification (RFID) technology, which is designed to provide ...
