Abstract
Environmental sensor circuit for a portable connected wireless device. The circuit includes a capacitive proximity sensor that determines when a user is close to the portable device. The device also has a magnetic field probe that provides a signal that indicates the position of a permanent magnet. The sensor circuit integrates both a digitizing unit and digital signal processing for the suppression of noise and drive in signals coming from the proximity sensor and from the magnetic field probe.
