Abstract
A capacitive door sensor includes an insulating plate that is located on a first leaf of a hinge that includes the first leaf and a second leaf. The capacitive door sensor further includes a first conductive plate that is located on the insulating plate. The capacitive door sensor further includes a second conductive plate that is located on the insulating plate and that is separate and spaced apart from the first conductive plate. The capacitive door sensor further includes a capacitance sensor that is electrically connected to the first conductive plate, that is electrically connected to the second conductive plate, and that is configured to detect a change in capacitance between the first conductive plate and the second conductive plate.
