1. A module for attachment to an injection device, the module comprising:
a housing attached to a surface of the injection device;
a sensor attached to the housing, the sensor being configured to detect a signal associated with an amount of medicament within the injection device and to generate a sensor signal based on the signal;
a control component coupled to the sensor, the control component being configured to harvest energy to process the sensor signal and to generate injection device data, wherein the control component comprises an energy harvester configured to harvest the energy in response to receiving a trigger signal, the trigger signal including a priming operation of the injection device and an interrogation signal; and
an antenna coupled to the control component and configured to transmit a radio frequency (RF) signal based on the injection device data.
