Abstract

A particulate detector system is provided that can sense particulates (such as smoke in the air). The system employs a reflected light system that generally avoids making measurements of light intensity. Instead, coded signals are compared with one another to determine error rates between emitted light and detected light (across a chamber). Based on the error rate, processing circuitry can determine particulate concentration.
