Abstract
Combustible gases, such as propane and methane-based city gas, are widely used in many homes and factories. However, accidents caused by gas leakage have become a menace to everyday life. Therefore, we have developed a simple and safe optical sensor for detecting leaking gas, which consists of plastic optical fiber (POF) coated with swelling polymer as a sensitive cladding layer. In experiments, a gas concentration below 3% was detected for both propane and methane gas. However, it was also confirmed that this system is influenced by humidity. Therefore, further improvement of the POF gas-sensing system with a POF humidity calibrator is proposed and discussed in this paper.
