Abstract
A sensor comprising a thin film photovoltaic pixel is fitted with optics to provide a field-of-view for the sensing of persons, or other objects, entering or exiting said field-of-view. When a person enters the field-of-view, a processor may sense such entry, then provide signals to other electronic apparatus indicative of such an event.
