Abstract
An ambient air condition sensor housing includes a front portion releasably coupled to a rear portion and defining an interior space therebetween adapted to retain at least one ambient air condition sensor. The rear portion defines apertures for passage of the ambient air therethrough. A labyrinth having a plurality of spaced apart upstanding walls is integrally attached to an inner surface of the rear portion and is positioned so as to cooperate with the air condition sensor. Each wall of the labyrinth includes a slightly arcuate configuration for funneling the ambient air toward the air condition sensor. The rear portion and labyrinth are completely covered with a black coating so as to minimize light reflectivity within the interior space whereby to enhance proper functioning of the air sensor.
