Abstract
A capacitive proximity sensor including a detection circuit, including a detection capacitor, a storage capacitor and switches, a DC voltage generator and a microcontroller which is configured to control the switches and to: obtain a voltage value across the terminals of the storage capacitor and across the terminals of the detection capacitor; calculate a first average defined by the average of the voltage values which are obtained at the end of each iteration of a first acquisition phase and a second average defined by the average of the voltage values at the end of each iteration of a second acquisition phase; and detect a human presence when the difference between the first average and the second average is above a predefined detection threshold.
