SMOKE DETECTOR DEVICE WITH SECONDARY DETECTION CHAMBER AND FILTER

Devices, systems, and methods for providing a smoke detector device with a secondary detection chamber and filter are described herein. One smoke detector device includes a first smoke detecting chamber, a first light source, a first light sensor, an air movement device to move at least some of the particulate into an inlet of a second smoke detecting chamber, a filter material positioned such that the particulate must pass through the filter material to enter the second chamber, the second chamber formed therein to receive particulate from the first chamber, a second light source, and a second light sensor to determine whether smoke particles are present in the second chamber.
