Modular sensor system having a housing with snap fit features

A modular sensor system comprising:

• a sensor housing comprising:
• a sidewall that defines an inner cavity that is configured to house a sensor device therein, a portion of the sidewall defining flexible snap fit features that are configured to couple the sensor housing with a luminaire and decouple the sensor housing from the luminaire,
• wherein the luminaire comprises a luminaire cavity that is configured to receive and removably couple the sensor housing therein;
• and
• a flange that is disposed at one end of the sidewall, a portion of the flange extending into the cavity to support the sensor device thereon.

A luminaire comprising:

• a housing that has a sensor receiving opening formed in a portion thereof, the portion being exposed to an area that is to be illuminated by the luminaire;
• a receptacle that is coupled to the luminaire such that the receptacle extends into the luminaire through the sensor receiving opening, the receptacle comprising a first inner cavity that is defined by a top wall comprising a first slot and a first side wall comprising a pair of second slots;
• and
• a sensor housing that is removably coupled to the receptacle and disposed in the first inner cavity, the sensor housing comprising:
• a second side wall that comprises a pair of curved cantilever snap fit assemblies formed therein and a locking tab extending from a top edge of the second side wall,
• wherein the pair of curved cantilever snap fit assemblies are configured to engage with the pair of second slots in the receptacle and the locking tab is configured to engage with the first slot when the sensor housing is removably coupled to the receptacle.
