Inhalation device with integrated electronics

An electronics module for an inhaler, the electronics module comprising:

• a power supply, a wireless communication circuit, a switch, a sensor, and a processor, wherein the processor is configured to:
• cause the electronics module to transition from a sleep state to an active state in response to actuation of the switch, wherein the electronics module is configured to provide power to the wireless communication circuit and the switch when in the sleep state, and wherein the electronics module is configured to provide power to the sensor, the processor and the wireless communication circuit when in the active state;
• generate a lever actuation event in response to actuation of a lever of the inhaler, wherein the lever is configured to advance a dose of medication on a flexible strip when the lever is moved from a first position to a second position;
• generate an inhalation event that indicates a flow rate of an inhalation by a user based on feedback from the sensor;
• and
• transmit the lever actuation event and the inhalation event to an external device using the wireless communication circuit.
