Abstract

Methods and systems are described for determining operation of an openable barrier into a building. A method for determining an open state of a barrier may include identifying a first position for the barrier, the barrier having at least one hinge and a hinge sensor magnetically mounted to the at least one hinge. The method may further include determining, based at least in part on the hinge sensor, when the barrier changes position from the first position to a second position. The method may further include wirelessly transmitting data concerning the change in position of the barrier.

Claims

1. A method for determining an open state of a barrier, comprising:

identifying a first position for the barrier, the barrier having at least one hinge and a hinge sensor magnetically mounted to the at least one hinge;

determining, based at least in part on the hinge sensor, when the barrier changes position from the first position to a second position; and

wirelessly transmitting data concerning the change in position of the barrier.

2. The method of claim 1, further comprising:

determining movement of the barrier with a motion sensor.

3. The method of claim 1, wherein the hinge sensor comprises a fixed portion, the method further comprising:

fixing a position of the fixed portion relative to the at least one hinge;

determining with the hinge sensor when the barrier is in a closed position; and

detecting with the hinge sensor when the barrier changes position from the closed position.

4. The method of claim 3, wherein the fixed portion of the hinge sensor comprises a spring-loaded sensor.

5. The method of claim 1, wherein the hinge sensor comprises a rotatable portion and a fixed portion, the method further comprising:

fixing a position of the fixed portion relative to the at least one hinge; and

rotatably mounting the rotatable portion to the fixed portion, the rotatable portion being arranged in contact with and movable by the barrier.

6. The method of claim 5, wherein the hinge sensor comprises a motion sensor, the motion sensor being mounted to the fixed portion.

7. The method of claim 6, further comprising:

determining with the motion sensor when an object moves through an opening that is controlled by the barrier.

8. The method of claim 1, wherein the first position is a closed position, and the second position is an open position.

9. The method of claim 1, wherein the first position is a first open position, and the second position is a second open position.

10. The method of claim 1, further comprising:

determining at least one of the first and second positions.

11. A sensor assembly for use with a barrier, comprising:

a fixed portion configured to maintain a fixed position relative to a hinge of the barrier to which the sensor assembly is magnetically mounted; and

a rotatable portion pivotally connected to the fixed portion and arranged to contact the barrier;

wherein the sensor assembly is operable to determine a position of the barrier based on at least one of a relative position between the fixed and rotatable portions and a change in position of the rotatable portion.

12. The sensor assembly of claim 11, further comprising:

a battery power source.

13. The sensor assembly of claim 11, further comprising:

a wireless transmitter configured to transmit data concerning the sensed position of the barrier.

14. The sensor assembly of claim 11, wherein the sensor assembly is operable to determine an amount the barrier is open relative to a closed position.

15. A barrier position detecting apparatus, comprising:

a mounting portion configured to releaseably magnetically mount a sensor assembly to a hinge of a barrier;

a fixed portion configured to maintain a fixed position relative to the hinge;

a movable portion arranged to contact the barrier at least when the barrier moves, the movable portion being movable relative to the fixed portion; and

a transmitter configured to wirelessly transfer data about a position of the barrier based on at least one of a relative position between the fixed and movable portions and a change in position of the movable portion.

16. The apparatus of claim 15, wherein the movable portion is biased into contact with the barrier.

17. The apparatus of claim 15, further comprising:

at least one motion sensor.

18. The apparatus of claim 17, wherein the at least one motion sensor comprises a passive infrared sensor.

19. The apparatus of claim 15, further comprising:

a potentiometer configured to determine a rotated position of the movable portion relative to the fixed portion.

20. The apparatus of claim 15, further comprising:

a piezoelectric sensor configured to measure an electrical charge generated from a force applied to the movable portion by the barrier when the barrier moves.
