US Patent 8941483 Heating appliance emergency reminder detection device

A device uses motion detection and heat detection to monitor a room and heating appliance and to remind a user to check on the appliance after a period of time. A motion detector sensor observes motion within a room or area by the heating appliance. If someone is in the area, then the device resets itself. If no one is detected, then the device alerts a user if heat is detected by a heat sensor. The alert prevents a possible heating or cooking emergency.
