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 ...

We present a BOTDA system based on dark-pulse scattering that provides improved resolution, accuracy, and acquisition time over conventional BOTDA systems, without the severe limitations on sensing ...

The micro sensor showed quick, stable, and high sensor responses to toluene at ppm (parts per million) concentrations at 300 °C even by operating the micro heater in a pulse-heating mode where ...

The device uses an ultrasonic sensor to detect nearby obstacles and provides real-time audio feedback, helping users navigate their environment more safely and independently.

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 ...
