1. A data collection device comprising:
an attachment assembly for attaching the data collection device to a dose setting dial of a medicament administration device, the dose setting dial disposed at a proximal end of the medicament administration device;
a light source configured to illuminate a portion of an internal component of the medicament administration device, the internal component comprising a plurality of reflective regions formed on the internal component; and
an optical sensor configured to receive light reflected by the plurality of reflective regions,
wherein the light source and optical sensor are configured to be located proximally of the dose setting dial when the data collection device is attached to the dose setting dial such that a light path between the light source, internal component, and optical sensor passes through a proximal end surface of the dose setting dial.
