an electronic module in communication with the motion sensor for supplying an electrical source to the motion sensor and controlling the operation of a lamp in the light fixture, wherein the bracket includes

a C-shaped frame to route electrical wires between the light fixture lamp, the motion sensor and the electronic module, and an attachment point for fixedly attaching the movable sensor assembly to the C-shaped bracket, and at least two rods extending outward from the C-shaped bracket as the structural connection point between the lamp and the light fixture.

2. The adjustable motion sensor of claim 1 , wherein the at least two rods are hollow for routing the electrical wires through the hollow rods.

3. The adjustable motion sensor of claim 1 , wherein the rods are threaded at one end for mating engagement with threaded aperture in the C-shaped bracket.

4. The adjustable motion sensor of claim 1 , wherein the movable sensor assembly comprises:

a motion detector; and

a lens with a rectangular coverage area covering the motion detector to direct sensing beams from the motion detector to provide the rectangular coverage area.

5. The adjustable motion sensor of claim 4 , wherein the sensor adjustment comprises:

a sensor adjustment drive rotatable to apply a force to move the movable sensor assembly upward and downward; and

a head on an exterior end of the sensor adjustment drive accessible for a user to rotate the head to change the position of the motion sensor upward and downward.

6. The adjustable motion sensor of claim 5 , wherein the sensor mechanism further comprises:

a drive gear coupled with the sensor adjustment drive such that rotation of the sensor adjustment drive causes the movable sensor assembly to move to change the direction the motion detector is aiming.

7. An adjustable motion sensor for a light fixture comprising:

an outer housing connected to a light fixture frame;

a movable sensor assembly including a motion detector contained within the outer housing;

a lens covering a portion of the movable sensor assembly; and

a sensor adjustment coupled with the movable sensor assembly, the sensor adjustment accessible from an exterior of the outer housing to allow a user to adjust the sensor adjustment to cause the motion detector to move upward and downward, wherein the bracket includes

a C-shaped bracket to route electrical wires and at least two rods extending outward from the C-shaped bracket as a structural connection point between the light fixture frame and the light fixture.

8. The adjustable motion sensor of claim 7 , wherein the movable sensor assembly comprises:

a sensor drive mechanism coupled with the movable sensor assembly, the sensor drive mechanism accessible from an exterior of the outer housing to allow a user to adjust the sensor drive mechanism to cause the motion detector to move upward and downward.

9. The adjustable motion sensor of claim 8 , wherein the at least two rods are hollow for routing the electrical wires through the hollow rods.

10. The adjustable motion sensor of claim 8 , wherein the sensor adjustment mechanism comprises:

a sensor adjustment drive shaft rotatable to apply a force to move the movable sensor assembly to adjust a horizontal position of the motion detector housed within the movable sensor assembly upward and downward; and

a head on an exterior end of the sensor adjustment drive shaft accessible for a user to rotate the head to change the horizontal position of the motion detector upward and downward.

11. The adjustable motion sensor of claim 10 , wherein the sensor adjustment mechanism further comprises:

a drive gear coupled with the sensor adjustment drive such that rotation of the sensor adjustment drive causes the movable sensor assembly to change the direction the motion sensor is aiming.

12. The adjustable motion sensor of claim 10 , wherein the sensor adjustment mechanism comprises:

a drive gear on the adjustment drive shaft; and

a rack gear on the sensor housing.

13. A light fixture with an adjustable motion sensor comprising:

a light fixture frame with an outer housing located above or below a light socket within the light fixture frame;

a C-shaped bracket mechanically installable within the outer housing;

a sensor pod assembly connectable with the bracket;

a movable sensor assembly connectable to the sensor pod assembly;

a fixed window covering a portion of the outer housing in the path of the motion sensor sensing beams:

a sensor adjustment coupled with the movable sensor assembly, the sensor adjustment accessible from an exterior of the outer housing to allow a user to adjust the sensor adjustment to cause the movable motion sensor to move upward and downward; and

an electronic module in communication with the motion sensor and light socket for supplying an electrical source to the motion sensor and controlling the operation of a lamp in the light fixture lamp socket, wherein the C-shaped bracket is used to route electrical wires between the light socket, the moveable sensor assembly and the electronic module and at least two rods extending outward from the C-shaped bracket as a structural connection point between the light fixture and the light socket.

14. The adjustable motion sensor of claim 13 , wherein the movable sensor assembly has a rectangular coverage area.
