This project demonstrates an Arduino-based Human Following Robot using IR sensors and an ultrasonic sensor. The robot detects a human presence in front of it and follows smoothly while correcting its ...

This library is using a hardware interrupt to monitor Echo pin state change instead of using pulseIn function which pauses code execution. The library enables the user to use this sensor with only 2-3 ...

Abstract: An optical fiber ultrasonic coupling sensor enhanced by a resonant cavity is design and optimization in this work. By using the prestressed bonding method, the structure consists of optical ...

Abstract: The stress field of steel members in service is unevenly distributed under complicated loads. The existing single-path ultrasonic (SPU) sensors can only measure stress in a single ...
