The Raspberry Pi is a credit card-sized computer capable of running full-fledged Linux distributions such as Raspberry Pi OS, ...

In this Arduino Project, you will also learn how to build an Arduino smoke alarm that sends SMS Alerts without needing to rely on the GSM module. The Arduino UNO R4 will detect fire or smoke using the ...

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 ...

Abstract: Low frequency vibration measurements in composite materials using embedded optical fiber sensors are presented in this paper. The two types of fiber sensors embedded are a polarization ...

The system consists of an undersea optical interrogation module together with multiple fiber Bragg grating (FBG)-based sensors, particularly for the measurement of depth, vibration ... Science and ...

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 ...
