Abstract: A human body detecting sensor system includes a first electrode, a second electrode, a drive circuit, a detection circuit, and a comparison circuit. The second electrode is connected to the first electrode via a capacitor. The drive circuit generates a first signal having a prescribed frequency for driving the first electrode. The detection circuit detects a second signal generated at the second electrode in response to the first signal being supplied to the first electrode. The comparison circuit compares the first signal with the second signal. The comparison circuit detects a touch and/or an approach of an object, which has an impedance in a certain range corresponding to a human body, with respect to at least one of the first and second electrodes when a phase difference between the first signal and the second signal is within a prescribed range.
