发明名称 Mailbox and counter combination device
摘要 A mailbox and counter combination device for determining a number of times a mailbox has been opened includes a mailbox having an opening extending therein. A door is hingedly coupled to the mailbox such that the door may be selectively positioned in an open position or a closed position with respect to the opening. A sensor is adapted for detecting when the door is moved from the closed position to the open position. A processor is operationally coupled to the sensor and is adapted for recording a number of times the door is moved to the open position.
