1. A smoke detector comprising:
one or more sensors for sensing combustion products, said one or more sensors including an aerosol sensor, said one or more sensors each having a sensor data output; a microcontroller connected to said one or more sensor data outputs, the microcontroller configured to determine, using linear discriminant analysis, whether data from the sensor data outputs are categorized as fire indicating data, and to produce a fire indicating signal if the data from the sensor data outputs are categorized as fire indicating data, wherein the microcontroller is configured to store centroids for fire indicating data and for non-fire indicating data, the microcontroller being configured to compute discriminant coordinates for data from the one or more data sensors based upon linear discriminant analysis and to produce the fire indicating signal in an event the computed discriminant coordinates are nearer to a stored fire indicating centroid than a stored non-fire indicating centroid; and an alarm connected to the microcontroller that is operable to produce an audible alert in response to a fire indicating signal from the microcontroller. |
