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 ...

In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it ...

A common sight in ‘smart homes’, door sensors allow you to detect whether a door is closed or open, enabling the triggering ...

One of the latest ad­di­tions to the ex­tens­ive range of Baumer sensors is the NexSonic UF300, an ultra-compact 18mm flat ultrasonic sensor with a 3-meter sensing range and ideally suited to ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

This project implements a real-time closed-loop motor control system where motor speed is dynamically regulated based on obstacle distance. An ultrasonic sensor provides the reference input, an ...

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 ...

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 ...
