Abstract
A door position sensing system includes a door claw having first and second magnets mounted thereon, and a Hall sensor mounted so as to sense the magnetic fields of the first and second magnets. The first magnet is mounted in a door half-latch position, and the second magnet is mounted in a door full-latch position. A processor is responsive to the Hall sensor to provide outputs indicating the half-latch and full-latch positions of a door. The processor may also be arranged to indicate a door open position when neither magnet is near the sensor.
