The invention relates to an inhaler (10), comprising: - a housing (11); - an air channel (30), which extends in the housing (11), between at least one air inlet opening (32) and a suction opening (24); - a dosing element (21) for vaporizing or nebulizing liquid supplied by the dosing element (21), for addition to air flowing in the air channel; - an electronic control device (15); - an electronic data store (35); and - a sensor system (33) having a flow-measuring device (37) for measuring the volumetric and/or mass flow rate of the air flow flowing through the air channel (30). The electronic control device (15) is designed to capture a plurality of air flow measurement values over at least part of the duration of an inhalation draw by means of the flow-measuring device (37), to compare the plurality of air flow measurement values with a draw profile stored in the data store (35), and to output a control signal on the basis of the comparison of the plurality of air flow measurement values with the stored draw profile. |
