Integration of sensor components with light fixtures in hazardous environments

An intrinsically safe sensor device located in a hazardous environment and coupled to a light fixture, the intrinsically safe sensor device comprising:

• a housing comprising at least one wall that forms a cavity, wherein the housing is configured to be coupled to the light fixture;
• sensor circuitry disposed within the cavity;
• and
• a sensor coupled to the sensor circuitry,
• wherein the sensor circuitry is configured to be coupled to a sensor assembly disposed in the light fixture.

An electrical system located in a hazardous environment, the electrical system comprising:

• a light fixture, comprising:
• a light fixture housing comprising at least one wall that forms a light fixture cavity, wherein the light fixture housing meets applicable standards for the hazardous environment;
• a sensor assembly disposed within the light fixture cavity, wherein the sensor assembly comprises:
• a sensor power supply;
• and
• a sensor control module;
• and
• at least one light fixture component;
• and
• an intrinsically safe sensor device electrically coupled to the light fixture, wherein the intrinsically safe sensor device comprises:
• a sensor device housing comprising at least one wall that forms a sensor device cavity;
• sensor circuitry disposed within the sensor device cavity, wherein the sensor circuitry is communicably coupled to the sensor assembly of the light fixture:
• and
• a sensor coupled to the sensor circuitry.
