1. A waste compartment system for an aircraft, comprising:
a motor operated door;
a proximity sensor configured to sense an object near the door or approaching the door;
a control module operatively connected to the proximity sensor and configured to open the door in response to the proximity sensor sensing an object near the door, wherein the control module is configured to close the door after a preset time after the proximity sensor senses an object;
a fire detection device operatively connected to the control module and configured to indicate the presence of a fire within a waste compartment associated with the waste compartment system, wherein the control module is configured to close the door and to disable the proximity sensor and/or to disable the door regardless of the proximity sensor when a fire is indicated by the fire detection device.
