Abstract
A system and method for detecting smoke using a photoelectric sensor is disclosed herein. The smoke detector can comprise a photoelectric smoke detection system, a smoke detector memory, and a microprocessor. The photoelectric smoke detection system can comprise a low-frequency light source, a high-frequency light source, and a light sensor. The smoke detector memory can comprise a smoke detector application, a plurality of low-frequency smoke signatures, and a plurality of high-frequency smoke signatures. Each of the low-frequency smoke signatures can relate to how a low-frequency light interacts with one of a plurality of particulates. Each of the high-frequency smoke signatures can relate to how a high-frequency light interacts with one of the plurality of particulates. Each of the particulates can be indicative or non-indicative of a fire.
