1. A capacitance module, comprising:
a substrate,
a set of electrodes formed on the substrate where a first electrode of the set is aligned with a second electrode of the set;
a controller in communication with the set of electrodes;
memory having programmed instructions configured to cause the controller, when executed, to:
measure a change in capacitance; and
determine a tilt of an object within a proximity sense range to the substrate based, in part, on the measured change in capacitance;
wherein measuring a change in capacitance includes transmitting a positive signal with the first electrode and transmitting a negative signal with the second electrode.
