| Zusammenfassung: | Provided is a sensor 100 for detecting a fire in a monitoring area, including a detection space into which a detection target caused by the fire flows, a light emitting portion 71 configured to emit emission light for detecting the detection target into the detection space, a light receiving portion 72 configured to receive scattered light generated by the emission light scattered by the detection target inside the detection space, an ambient light processing portion configured to prevent ambient light from entering the detection space, and a disturbance light processing portion configured to process disturbance light other than the scattered light, the disturbance light being generated inside the detection space due to the emission light, in which the ambient light processing portion and the disturbance light processing portion are elements different from each other, the ambient light processing portion is provided outside the detection space, and the disturbance light processing portion is provided inside the detection space. |
