Abstract
A smoke detector includes a detector chamber, a number of emitters and at least one optical sensor. The optical sensor is built or realized as a multi-spectral optical sensor. The multi-spectral sensor includes a plurality of spectral filters for a plurality of spectral channels and at least one broadband channel. The plurality of spectral channels can be realized by photodiodes.
