A smoke detector that is insensitive to moisture, such as for use in aircraft cargo bays and the like, is provided. The smoke detector includes a housing defining a chamber that is sealed from outside light sources yet is capable of receiving smoke. The smoke detector also includes a light source that is positioned inside the chamber and a detector for receiving diffusely scattered light within the chamber. Advantageously, the smoke detector also includes a moisture compensating device that reflects a substantially consistent percentage of light incident thereupon regardless of moisture on the surfaces thereof such that the operation of the light source can be reliably tested even in environments where moisture has condensed or otherwise collected on the walls of the housing.
