A system for identifying forgotten items is disclosed. In embodiments, the system includes one or more item detectors (104). The item detectors (104) may be configured to determine a calibration value of a stowage area in a calibration mode, and further configured to determine a check value of the stowage area in a check mode. The system also includes a controller (114) configured to receive the calibration value and the check value, calculate a difference value between the calibration value and the check value, and compare the difference value to a threshold value. If the difference value is greater than the threshold value, the controller (114) is further configured to generate one or more found item signals which indicate the presence of a found forgotten item.
