Abstract
A detector device includes a light source disposed within a chamber, a sensor disposed within the chamber, a compensator circuit electrically coupled with the sensor, and a controller. The controller is operable to receive a sensor signal generated by the sensor, determine a compensation factor to adjust the sensor signal, and generate a compensation offset signal based on the compensation factor. The controller is further operable to output the compensation offset signal to the compensator circuit to produce a compensated sensor signal as an adjustment to the sensor signal, energize the light source, monitor the compensated sensor signal with respect to an alarm limit, and trigger an alarm event based on the compensated sensor signal exceeding the alarm limit.
