摘要:
The present disclosure relates to medicament injection devices. According to a first aspect, this disclosure describes an injection device comprising: a movable dosage programming component comprising a rotary encoder system having a predefined angular periodicity; a sensor arrangement comprising a first optical sensor configured to detect movement of the movable dosage programming component relative to the sensor arrangement during dosing of a medicament, wherein the first optical sensor is configured to operate in a strobe-sampling mode at a first frequency; a second optical sensor configured to detect movement of the rotary encoder system relative to the second optical sensor wherein the second optical sensor is configured to operate in a strobe-sampling mode at a second frequency lower than the first frequency; and a processor arrangement configured to, based on said detected movement, determine a medicament dosage administered by the injection device.
