Patent 10897887 was granted and assigned to Bell Laboratories, Inc. on January, 2021 by the United States Patent and Trademark Office.
A rodent bait station has an electronic sensor module protected within a sealed receptacle beneath a tray bottom wall. A threshold is defined by walls on the upper side of the tray. A rodent must pass over the threshold to reading a feeding portion of the tray which supports rodent bait. The sensor module has a capacitance sensor urged against the bottom wall of the tray and which detects the passing of a rodent into the feeding area. The incidence of the rodent is logged and made available to a device exterior of the tray.
