ABSTRACT:
A swimming pool skimmer includes a paddle wheel that directs fluid and debris into a debris catcher. The paddle wheel is turned by a motor that is powered from an array of solar cells. A solar concentrator focuses solar energy onto the solar cells, and an alarm circuit includes a strain gauge on the debris catcher. The strain gauge forms one leg of a bridge circuit that is connected to a comparator having a feedback loop. The output of the comparator is connected to an alarm element either directly or remotely.
