<br>We report a capacitance monitoring methodology for reaching arbitrary polarization rotation from nematic liquid crystals. By locking to the unique capacitance related to the molecular orientation, any polarization rotation can be achieved with improved accuracy over a wide temperature vary. A modified relaxation oscillator [iTagPro geofencing](https://localbusinessblogs.co.uk/wiki/index.php?title=The_Ultimate_Guide_To_Itagpro_Tracker:_Everything_You_Need_To_Know) circuit that may simultaneously determine the capacitance and drive the rotator is introduced.
