The result shows that different levels are not far away, sensor system to detect air humidity using polymer optical fiber (POF) Autonics FD-620-10 has been developed. The POF sensor is performed by stripping cladding of the fiber and then replace it with TiO2 -SiO2 . The stripping variations are 1 cm, 2 cm, and 3 cm. The sensor system is composed of a red diode laser with wave length 638 nm as light source and photodiode light detector. The output from the detector will be displayed on an electronic viewer such as LCD or PC. Data processing is carried out using an ADC to get transfer function to be embedded into Arduino Uno. The obtained regression equation is y = 0.131x - 22.58 and the coefficient of determination (R2 ) is 0.984. It is mean that the optical fiber sensor has a good linearity. The accuracy of the sensor is obtained from the comparison of the humidity gauge designed with a hygrometer (an existing humidity gauge). The error were generated by the designed device was 2.78%. The error results indicate that the percentage of errors from the designed device is relatively small, so it can be concluded that the humidity sensor can respond well to the measured humidity.</p> <p>&nbsp;</p> <p>&nbsp;</p> <p>Keywords: humidity, laser diode, photodiode, Plastic fiber optic, TiO2 -SiO2</p&gt;}, number={2}, journal={KnE Engineering}, author={., Febrielviyanti and ., Harmadi and Dahlan, Dahyunir and Rilda, Yetria and Herlin, Helmi Septaria}, year={2019}, month={Apr.}, pages={116–127} }
