Simultaneous monitoring of humidity and strain based on Bragg sensor

Monitoring of humidity and strain change has currently been used in great and numerous applications such as agriculture, civil engineering, chemical, automatic fire detection. By modeling the spectrum of optical fiber, we detect the variation of wavelength and then we can deduce about strain and temperature change. In order to simultaneously monitor humidity and strain, we involve mathematical model characterizing Fiber bragg grating sensor (FBGS) which will be implemented through Matlab codes. In this paper, we proposed to monitor simultaneous strain and humidity change using specifications and features of Bragg sensor. Therefore, by measuring humidity and strain we will investigate and deduce the relation between these parameters. (C) 2016 Elsevier GmbH. All rights reserved.
