Bonezegei_HCSR04 is a simple and easy-to-use Arduino library for interfacing HCSR04 ultrasonic sensor module. The library provides functions for measuring distance, setting trigger and echo pins. The ...

I purchased one of each of these cheap sensors recently from aliexpress for testing purposes. Compared with the ubiquitous HC-SR04 (*), I liked the idea of having a combined emitter/receiver, i.e.

Abstract: Stable operation of transformers is vital for the security of power grids. And the partial discharges can lead to insulation degradation and potential transformer failures. This paper ...

Abstract: The total focusing method (TFM) is an ultrasonic phased array imaging algorithm used in ultrasonic nondestructive testing (NDT) that processes large amounts of data from full matrix capture ...

具备无线传感与操控能力的智能微型系统，被认为是推动生物医学应用的重要方向。但在毫米乃至更小尺度上，传感与驱动往往互相“打架”，使系统难以同时做到小型化、稳定和高性能。研究团队提出一种“机器人传感器”，将嵌入式超声软传感器 ...
