11. A method comprising:

receiving, by a controller of an electronic device associated with a deterrent device, sensor data generated by a sensor of the electronic device, the sensor data associated with a sensing space that is positioned proximate to at least one of a grip of the deterrent device or an exterior surface of a trigger guard of the deterrent device,

the electronic device including a housing removably coupled to the deterrent device, and

the sensor being carried by the housing and positioned such that the sensing space extends, from the housing, to a location external to the housing and in a direction toward the grip of the deterrent device;

determining, by the controller and based at least in part on the sensor data, a presence of an object within at least a portion of the sensing space; and

activating, by the controller, an activatable system responsive to determining the presence of the object.

12. The method of claim 11 , further comprising:

receiving, by the controller, additional sensor data from the sensor;

determining, by the controller and based at least in part on the additional sensor data, an absence of the object within the sensing space; and

deactivating, by the controller, the activatable system responsive to determining the absence of the object.

13. The method of claim 11 , wherein the sensor is an optical proximity detection sensor.

14. The method of claim 11 , wherein the controller continuously activates the activatable system during a period of time in which the sensor data indicates the presence of the object.

15. The method of claim 11 , further comprising determining, by the controller and based at least in part on the sensor data, a detection value associated with the sensing space, wherein determining the presence of the object is based at least in part on a determination, by the controller, that the detection value meets or exceeds a threshold.

16. The method of claim 11 , wherein the sensor is at least one of an emitter that is configured to emit a first electromagnetic radiation or a detector that is configured to detect a second electromagnetic radiation.

17. The method of claim 11 , wherein the activatable system comprises at least one of a laser or a lamp.

18. The method of claim 11 , wherein the sensing space is at least one of:

below a volume defined by the trigger guard of the deterrent device and adjacent to a grip of the deterrent device;

disjointed from the volume defined by the trigger guard of the deterrent device; or

laterally adjacent to the trigger guard of the deterrent device.

19. A system comprising:

a deterrent device; and

an electronic device configured to detachably couple to the deterrent device, the electronic device comprising:

a housing separate from the deterrent device;

one or more processors disposed within the housing; and

one or more non-transitory computer-readable media storing instruction that, when executed, cause the one or more processors to perform operations comprising:

receiving sensor data generated by a sensor carried by the housing, the sensor data associated with a sensing space that is positioned proximate to at least one of a grip of the deterrent device or an exterior surface of a trigger guard of the deterrent device, the sensor being positioned such that the sensing space extends, from the housing, to a location external to the housing and in a direction toward the grip of the deterrent device;

determining, based at least in part on the sensor data, a presence of an object within at least a portion of the sensing space; and
