An aspirating detector system includes a detector and a controller. The detector includes a chamber, a light source adjacent the chamber, and a sensor adjacent the chamber. The sensor is operable to emit sensor signals responsive to received light from interaction of a light beam from the light source with an analyte in the chamber. The controller is connected to receive the sensor signals. The controller is configured to determine whether a target substance is present in the analyte based on an intensity of the received light.
