Abstract
A method for detecting smoke via a chamber-less smoke sensor includes applying one or more filters to eliminate a flooding of ambient light upon the smoke sensor and emitting, by a source, light. At least one detector detects at least a portion of the emitted light and a processor processes the detected light to signal an alarm condition when one or more threshold levels are reached. A chamber-less smoke sensor includes a light source configured to emit light and at least one detector configured to detect at least a portion of the emitted light. An electronic filter and/or a processor is configured to apply one or more filters to eliminate a flooding of ambient light upon the smoke sensor and process the detected light to signal an alarm condition when a threshold level is reached.
