The drop sensor generally comprises means for passively detecting the passage of packages, and means for generating the plurality of signals indicative of the deposit of such packages through the door. Such plurality of signals include a signal to indicate that the drop box is approaching a "full box" condition, a signal to indicate that the drop box is at such "full box" condition, and a "pickup" signal to indicate that the courier has completed his daily rounds.
