Surrounding refractive index and liquid based sensors using fibre bragg grating

Fiber Bragg grating (FBG) becomes one of the favourable sensing elements in current technology. In this study, FBG was chosen as the temperature sensor to validate the performance in different liquid samples and surrounding refractive index (SRI). FBG was chosen for the purpose due to its super sensitive sensor, low in cost, minimal of data loss, and other outstanding advantages. The experiment was done in difference sample of liquids, SRI, and condition. The sensitivity of FBG in air, water, and stingless bee honey were recorded at 10.6892 nm/°C, 10.6247 nm/°C, and 13.3985 nm/°C respectively.It shows that FBG is suit as a temperature sensor in different medium and SRI
