Abstract

Development of Fiber-Optic Humidity Sensor Probe with Gelatin Cladding. Humidity sensor based on optical fiber with gelatin cladding has been developed. In this humidity sensor probe, the origin cladding of optical fiber is replaced by gelatin coating as humidity sensitive cladding. Testing of the optical fiber sensor probe was conducted by measuring of light intensity transmitted on the optical fiber probe for each variation of different humidity treatments. Response of the optical fiber sensor probe measured from 42%RH to 99%RH, the results show an optical transmission curve varied with relative humidity (RH). Optical transmission in the optical fiber probe increase with RH value at a specific wavelength range, that is from green to red spectrum bands (500 nm – 700 nm), where a significant variation from 600 nm to 650 nm in yellow to red spectrum bands. Wavelength where is a maximum intensity of optical transmission occurs at 610 nm. Therefore, the optical fiber humidity sensor probe could response humidity form 42%RH to 99%RH with the best response in humidity range of 60%RH to 72%RH that is have a good linearity and sensitivity.

Abstract

Humidity Dependence of Optical Properties of Gelatin Films. Humidity dependence of optical properties of gelatin films prepared by casting technique has been investigated. Gelatin films was investigated its optical properties to varied humidity condition. Optical responses investigated are optical transmission and absorption at visible light spectrum measured utilizing a UV-Vis (Ultraviolet – Visible) spectrophotometer. The results of optical transmittance and absorbance obtained shows an optical response of gelatin films in widely visible light spectrum within range 530 – 680 nm, with most clearly response in a spectrum band in 580 – 650 nm. Different humidity treatment cause a significantly change of optical characteristics, that is the transmittance and absorbance change in to humidity. Transmittance of gelatin films increase with increasing humidity in a range 580 – 650 nm, in contrast with absorbance that is decrease with increasing humidity. Plot of transmission and absorption intensity with varied humidity from 37%RH to 99%RH at 610 nm exhibited a good linearity. Two samples showed same characteristics
