Developing a Gold coated Fiber Brag Grating (FBG) sensor to monitor chlorine levels in water

Abstract

Monitoring chlorine levels in water are crucial to prevent health risks in humans. This study investigated designing a sensitive FBG sensor to measure chlorine levels in water in ppm. The overall sensing mechanism provides advantages like; small features, high resolution, and sensing along the whole fiber length; the results were promising, and the sensor provided minimal chlorine levels detection in the water, with a detection range was between (1 -10) ppm, making it sufficient for the study.
