Abstract
A capacitor based sensor for angular position detection having two fixed plates arranged at an angle and a semicircular rotating plate in between. The sensor can determine any angular position in the full 0-360 degrees range. The sensor may be temperature compensated, and integrated with electronics such that sensor module only has two electrical leads, one for input power and one for input/output digital data. A method for converting capacitance measurements to an angle is also disclosed.
