This is an Arduino library for SDI-12 communication with a wide variety of environmental sensors. It provides a general software solution, without requiring any additional hardware, to implement the ...

Abstract: We report on what we believe to be the first truly distributed fiber vibration sensor based on pulse base Brillouin optical time-domain analysis (BOTDA). The pulse base approach is used to ...

Abstract: In this letter, a novel multilongitudinal mode fiber-optic vibration sensor is presented. The beat frequency of any two different laser modes is modulated by the vibration signal. The ...
