Abstract
A non-contact object detection system includes a capacitor sensor and a control system, the control system providing a AES (Adaptive Excitation Signal) to the capacitor sensor, the AES (Adaptive Excitation Signal) configured according to an environment in which the capacitor sensor is deployed, the AES (Adaptive Excitation Signal) configured to produce a threshold voltage from the capacitor sensor to the control system in the environment when an object is not in a detection area of the capacitor sensor.
