ABSTRACT:
A trash enclosure includes a bay with a moveable lid and a sensor attached to the inner periphery of the bay. The moveable lid attaches to the enclosure and moves between an open position and a closed position to cover the bay. Upon detection of an object within the bay, the sensor causes the lid to open. Accordingly, the inner periphery shields the sensor to inhibit detection of objects beyond the inner periphery.
