15. An electrical assembly for detecting occupancy for operation of a light fixture, the electrical assembly comprising:
an antenna assembly that sends and receives radio frequency signals; and
an occupancy sensor coupled to the antenna assembly, wherein the occupancy sensor generates the signals that are sent by the antenna assembly, wherein the occupancy sensor interprets the signals that are received by the antenna assembly,
wherein at least a portion of the antenna assembly is configured to be integrated with an exposed component of the light fixture, wherein the exposed component has a substantially unobstructed line of sight with the ambient environment.
16. The electrical assembly of claim 15 , wherein the antenna assembly comprises an antenna and a connection tail coupled to the antenna, wherein the antenna is configured to be printed onto the exposed component of the light fixture.
17. The electrical assembly of claim 16 , wherein at least a portion of the connection tail is further printed onto the exposed component of the light fixture.
18. The electrical assembly of claim 15 , wherein the electrical assembly further comprises:
at least one communication link that facilitates communication between the antenna assembly and the occupancy sensor.
19. The electrical assembly of claim 15 , wherein at least one measurement made by the occupancy sensor is configured to be used to operate the light fixture.
20. A light fixture disposed in an ambient environment, wherein the light fixture comprises:
at least one light source;
a sensor module that measures a parameter, wherein the parameter is used to operate the at least one light source; and
an antenna assembly coupled to the sensor module, wherein at least a portion of the antenna assembly is disposed on an exposed component, wherein the exposed component has a substantially unobstructed line of sight with the ambient environment, wherein the antenna assembly is used to transmit at least one communication signal in the ambient environment, wherein the at least one communication signal is associated with a measurement of the parameter made by the sensor module.
