The Time of Flight (ToF) sensor is significantly more accurate than the ultrasonic sensor. This is evident through the data shown above. Although the measurements were generally smaller than realistic ...

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 ...
