Abstract: A capacitive proximity sensor may include a proximity sensing capacitor to provide a voltage output based on a voltage input, the capacitor including a ground plane and an electrode loop capacitively coupled to the ground plane. The proximity sensor may include a processor to detect an object proximity based on a change in the voltage output. This proximity sensor provides automated detection of a person, and thereby reduces the need for a vehicle occupant or child caregiver to activate a sensor by pressing a button. The use of a capacitance-based proximity sensor reduces issues associated with fabric, clothing, or other materials separating the proximity sensor from a person.
