This project demonstrates a low-cost intelligent traffic signal system using Arduino and ultrasonic sensors to reduce congestion caused by fixed-timer traffic lights. Four HC-SR04 sensors detect ...

An open-source Arduino and Flutter-based wearable system that provides voice-guided navigation, object and text recognition, and obstacle detection to assist visually impaired individuals in daily ...

Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (January 2026) that make the cut: ...

Abstract: We propose a one-millimeter-scale linear ultrasonic motor and its feedback control system with a Hall sensor. The size of the stator measures 1.6 mm in height, 1.6 mm in width, and 0.3 mm in ...

Abstract: Proximity sensing is of great importance for robot control during human–robot collaboration (HRC). Commonly used machine vision sensors or photodetectors are subjected to the light block ...

This radar is closely related to defense technology, where this tool can function as a determinant of the direction of movement / position / shape of a detected object. The purpose of this project is ...
