Sensor module with a collar
Various aspects of the present disclosure generally relate to a sensor module. In some aspects, a sensor module may include a collar configured to be attached to a camera module for a user device. The collar may include a first opening that is configured to align with an aperture of a camera of the camera module, and a second opening. The sensor module may include a sensor embedded in the collar. The sensor may be aligned with the second opening of the collar. Numerous other aspects are provided.
1. A sensor module comprising:
a collar configured to be attached to a camera module for a 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 within the sensor attachment module,
wherein the sensor is in an offset position relative to an axis associated with the sensor module; and
a reflective device configured to redirect a field of view of the sensor through the aperture.
2. The sensor module of claim 1 , wherein the axis is a center axis of the second opening.
3. The sensor module of claim 1 , further comprising:
an optic device configured to define the field of view of the sensor.
4. The sensor module of claim 3 , wherein the optic device is one of a lens or a prism.
5. The sensor module of claim 3 , wherein the optic device is within the sensor attachment module.
6. The sensor module of claim 1 , wherein the sensor is a sensor array.
7. The sensor module of claim 1 , further comprising:
a light emitter that is configured to transmit light that is redirected towards the sensor.
8. The sensor module of claim 1 , wherein a height of the collar is substantially equal to a height of a lens unit of the camera.
9. The sensor module of claim 1 , wherein the sensor requires less than 10 milliwatts (mW) of power to operate.
10. The sensor module of claim 1 , wherein the sensor enables an always-on detection capability without a user interacting with the user device.
11. 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, that is capable of performing always-on detection when an environment is dark,
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.
12. The system of claim 11 , wherein the sensor requires less power than the camera.
13. The system of claim 11 , wherein the sensor and the camera use power from a battery of the user device.
14. The system of claim 11 , wherein the sensor enables an always-on detection capability without a user interacting with the user device.
15. The system of claim 11 , wherein the sensor is an infrared sensor.
16. A user device, comprising:
a collar,
wherein the collar includes:
a first opening that is configured to align with an aperture of a camera, and
a second opening;
a sensor,
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, configured to redirect a field of view of the sensor through the aperture.
17. The user device of claim 16 , further comprising:
an optic device configured to define the field of view of the sensor.
18. The user device of claim 16 , further comprising:
a light emitter that is configured to emit light that is redirected towards the sensor.
19. The user device of claim 16 , wherein a height of the collar is substantially equal to a height of a lens unit of the camera.
20. The user device of claim 16 , wherein the sensor is capable of performing always-on detection when an environment is dark.
