Zusammenfassung:	A smoke detection apparatus based on multiple wavelengths is provided, which includes: a chamber configured to receive an inflow of a smoke; a detector including a light emitter having a plurality of light sources that radiate light having a plurality of different wavelengths into a space in the chamber, and a light receiver configured to receive scattered light by the plurality of light sources; and a controller configured to control an operation of the detector and to distinguish between fire smoke and non-fire quasi-smoke by detecting and analyzing a light receiving signal of the light receiver.
