1. A lighting system, comprising:
- a light fixture located in a hazardous environment, wherein the light fixture comprises a controller; and
a sensor module communicably coupled to the controller of the light fixture, wherein the sensor module comprises a sensor module housing and a sensor disposed within the sensor module housing, wherein the sensor module housing comprises a first coupling feature that is configured to couple to a second coupling feature of a hazardous location enclosure, wherein the first coupling feature comprises at least one sealing member disposed within at least one first channel in an exterior surface of the sensor module housing,wherein the hazardous location enclosure and the sensor module, when coupled to each other, comply with applicable standards for the hazardous environment,wherein the at least one sealing member is configured to contact the hazardous location enclosure without engaging the second coupling feature of the hazardous location enclosure when the sensor module is coupled to the hazardous location enclosure.

Abstract
A lighting system can include a light fixture located in a hazardous environment, wherein the light fixture comprises a controller. The light fixture can also include a sensor module communicably coupled to the controller of the light fixture, wherein the sensor module comprises a sensor module housing and a sensor disposed within the sensor module housing, wherein the sensor module housing comprises a first coupling feature that couples to a hazardous location enclosure. The hazardous location enclosure and the sensor module, when coupled to each other, can comply with applicable standards for the hazardous environment.

18. A lighting system, comprising:
-
a light fixture located in a hazardous environment, wherein the light fixture comprises a controller and a first coupling feature disposed on a light fixture housing; and a sensor module communicably coupled to the controller of the light fixture, wherein the sensor module is also electrically and mechanically coupled to the light fixture housing, wherein the sensor module comprises a sensor module housing and a sensor disposed within the sensor module housing, wherein the sensor module housing comprises a second coupling feature that electrically and mechanically couples to the first coupling feature, wherein the first coupling feature comprises a physical barrier and an electrical connector, wherein the physical barrier prevents the light fixture from being compromised if the sensor module fails when the sensor module is coupled to the light fixture, wherein the electrical connector protrudes through the physical barrier.

19. A lighting system, comprising:
-
a light fixture located in a hazardous environment, wherein the light fixture comprises a controller and a first coupling feature disposed on a light fixture housing; and a sensor module communicably coupled to the controller of the light fixture, wherein the sensor module is also electrically and mechanically coupled to the light fixture housing, wherein the sensor module comprises a sensor module housing and a sensor disposed within the sensor module housing, wherein the sensor module housing comprises a second coupling feature that electrically and mechanically couples to the first coupling feature, wherein the first coupling feature couples to and decouples from the second coupling feature without use of tools, wherein the first coupling feature and the second coupling feature allow for a user to adjust a position of the sensor module relative to the light fixture housing within a range of positions when the sensor module is coupled to the light fixture while still complying with applicable standards for the hazardous environment.
