The apparatus for sensing plural gases is substantially a gas sensor adopting planar lightwave circuit for constructing reference optical path and sensing optical path, which is a flat structure with abilities of high accuracy, long-term stability, and short response time. The gas sensor can be widely applied for monitoring the safety of a working environment, securing the safety of workers, alerting potential hazard in a factory, inspecting harmful materials in a specific area, testing leakage of a pipeline, inspecting waste gas exhausted from automobile/motorcycle, and monitoring the living quality of household environment.
