description Apparatuses and methods of high-distance directional proximity sensors are described. One apparatus includes at least three electrodes in a sensor layer, an electrode in a shield layer, and an insulator located between the layers. A processing device is configured to scan the at least three electrodes over a period of time to obtain a digital signal for each of the at least three electrodes while driving a shield signal on the electrode of the shield layer. The processing device detects a gesture by an object using the digital signals. The processing device measures an amplitude value of the digital signal for each of the at least three electrodes and outputs an indication of the gesture responsive to a ratio of a highest amplitude value and a lowest amplitude value satisfying a first threshold criterion that represents the object being within a proximity detection area above the sensor layer.
