1. A data collection device comprising:
a distal end, the distal end being open to allow the data collection device to be mounted on a rotatable dose setting dial of a medicament administration device;
a proximal end, the proximal end being closed;
a light source configured to project light from the distal end of the data collection device; and
an optical sensor, wherein when the data collection device is mounted on the dose setting dial of the medicament administration device:
the distal end of the data collection device faces a surface of at least one outward radial protrusion extending beyond an external surface of an external housing of the medicament administration device and the light source is configured to illuminate a portion of the surface of the at least one outward radial protrusion, wherein the at least one outward radial protrusion is located distally with respect to the data collection device and is part of a dial sleeve of the medicament administration device located partially inside the external housing of the medicament administration device and configured to rotate when a dose is dialed; and the optical sensor faces the surface of the at least one outward radial protrusion of the dial sleeve and is configured to receive light reflected by at least relatively reflective regions disposed on the surface of the at least one outward radial protrusion of the dial sleeve.
