1. A moisture sensing assembly for mounting on one surface of a window to detect and indicate moisture or other particles accumulated on the opposite surface of the window, the window having inside and outside surfaces, said assembly comprising:

  • emitter means for emitting radiant energy toward the window;

    detector means for detecting and receiving radiant energy from said emitter means after reflection and refraction by the window and any accumulated moisture or particles on the outside surface of the window;

    support means for supporting said emitter means and detector means in spaced angular relationship to one another;

    a mounting member for attachment to the inside window surface;

    mounting means for engaging said mounting member and releasably mounting said support means on the inside window surface including biasing means for resiliently holding said support means against the inside window surface with said emitter means at a predetermined incident angle and said deflector means at a predetermined reflection angle; and

    releasable locking means on at least one of said mounting member and said mounting means for holding said mounting member and mounting means together until released.
