1. 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 sensor and a second sensor configured to detect movement of the rotary encoder system relative to the sensor arrangement during dispensing of a medicament, wherein the first sensor and the second sensor are configured to operate in a strobe-sampling mode in which each of the sensors is switched on and off intermittently at a controlled frequency; and
a processor arrangement configured to, based on the movement, determine a medicament dosage administered by the injection device.
