Abstract: A modular troffer luminaire includes a housing having a perimeter frame, and a first light module removably attached to the housing. The first light module is replaceable by a second light module after the modular troffer luminaire is installed, where the first light module comprises an LED light source and an optic. The modular troffer luminaire further includes a sensor attached to the perimeter frame. The first light module is controllable based on sensing information from the sensor.

Abstract: A signal guide for a sensor device is disclosed herein. The signal guide can include a base having a first proximal aperture, where the first proximal aperture has a first cross-sectional profile, where the first proximal aperture is configured to be disposed proximate to a first transceiver element of the sensor device. The signal guide can also include a body disposed adjacent to the base, wherein the body comprises a first main channel that adjoins the first proximal aperture. The signal guide can further include a distal end disposed adjacent to the body opposite the base, where the distal end includes a first distal aperture that adjoins the first main channel, where the first distal aperture has a second cross-sectional profile, where the first distal aperture is configured to be disposed proximate to an ambient environment.

Abstract: A signal barrier for a sensor device can include at least one wall that forms an inner space, wherein the at least one wall comprises a material for reducing an amount of a signal from entering the inner space, wherein the at least one wall is configured to be disposed adjacent to a transceiver element of the sensor device, wherein the transceiver element is directed to the inner space.
