1. A method of detecting proximity, comprising:

  • providing a proximity sensor;

    coupling a capacitive sensing element to the proximity sensor;

    determining a compensation value of the proximity sensor;

    comparing the compensation value to a reference compensation value to determine validity of the compensation value; and

    measuring a self-capacitance of the capacitive sensing element with the proximity sensor using the compensation value as an offset.
