A capacitive sensor including a pendulum for electronically determining an indication of angular offset and a capacitive leveling device having such a capacitive sensor for leveling an associated reference surface. The capacitive sensor detects a difference in capacitance of one or more capacitors on the pendulum and its housing, each capacitor having a first electrode movable apart from a second electrode as the housing tilts relative to the pendulum.
