Sensor module with a collar configured to be attached to a camera module for a user device

A system for a user device, the system comprising:

• a camera, wherein the camera comprises:
• an aperture, and a lens unit that includes a lens;
• a structure configured to support the camera;
• a collar configured to be attached to the structure;
• a sensor attachment module;
• a sensor, within the sensor attachment module, with an always-on detection capability,
• wherein the sensor is in an offset position relative to an axis of an opening of the collar, and a reflective device that redirects light towards the sensor, wherein the light enters a second opening in a direction that is parallel relative to the axis of the opening of the collar and is redirected in a direction that is perpendicular to the axis o the opening of the collar.

A communication module of a user device, the communication module comprising:

• a collar configured to be attached to a camera module of the user device,
• wherein the collar includes:
• a first opening that is configured to align with an aperture of a camera of the camera module, and
• a second opening;
• a sensor attachment module in the collar;
• a sensor in the sensor attachment module,
• wherein the sensor is in an offset position relative to an axis of symmetry associated with the collar;
• and
• a reflective device, in the collar, that redirects light towards the sensor,
• wherein the light enters the second opening in a direction that is parallel relative to the axis of symmetry and is redirected in a direction that is perpendicular to the axis of symmetry.

A user device comprising:

• a camera module that includes a camera,
• wherein the camera comprises:
• an aperture, and
