Abstract
This research produces plastic fiber optic sensors to detect gasoline and diesel vapors. The sensor consists of a single-mode optical fiber which has removed the original 3 cm long cladding in the center and replaced with Stannic Oxide (SnO2). The modified cladding coated with SnO2 can produce attenuation changes at the core and cladding boundaries (evanescent field). This attenuation change is in line with changes in light intensity when interacting with gasoline and diesel vapors. The optical fiber sensor can respond to the concentration of gasoline vapors, with the most optimal sensor sensitivity value being 0.0821 volts/°C at 50 ppm. At the same time, the response to diesel vapors has a sensitivity value of -0.0262 volts/°C at a concentration of 50 ppm. There is a difference in the response of the fiber optic sensor when interacting with gasoline and diesel vapors. When interacting with gasoline vapors, the higher the vapor concentration, the less light intensity received by the OTDR. The higher the concentration of diesel vapor given, the more light intensity received by the OTDR.
