Abstract

A rain sensor includes a pair of spaced apart parallel conductive rods. The conductive rods are mounted in an insulated housing. The housing includes a pair of angled top wall members which are spaced apart to define a slot, the slot being in an area directly above and parallel to the electrodes. Moisture falling on the housing top wall is collected and directed to the area between the conductive rods.

Claims

1. A rain sensor comprising:

a pair of spaced apart parallel conductive rods;

a housing for mounting said conductive rods therein; and

said housing including a pair of angled top wall members spaced apart to define a slot, said slot being in an area directly above, parallel to and spaced from said conductive rods for enabling moisture falling on said housing top wall to be directed to the area between said conductive rods, said conductive rods being spaced apart a distance slightly less than the width of said slot.

2. A rain sensor in accordance with claim 1 wherein said angled top wall members each extend downwardly toward said slot.
