1. A hinge system comprising:
a hinge bracket having an axis extending therethrough;
a first magnet coupled to the hinge bracket and configured to rotate about the axis of the hinge bracket from a first position to a second position, the first magnet having first and second poles;
a rotatable member coupled to the hinge bracket and the first magnet;
a second magnet spaced a pre-determined distance away from the first magnet and having first and second poles, wherein the first pole of each of the first and second magnets faces in a direction toward one another; and
a position sensor configured to detect a location of the first magnet,
wherein when the first pole of the first magnet is at a first angle relative to the first pole of the second magnet, the first magnet and the second magnet are in the first position and the rotatable member is in a closed position relative to the hinge bracket, and
wherein when the first pole of the first magnet is at a second angle relative to the first pole of the second magnet, the first magnet and the second magnet are in the second position, and the rotatable member is rotated to an open position relative to the hinge bracket.
