Inhalation device controller

An inhalation device controller configured to control an atomizer including a container configured to hold an aerosol source of a liquid, a heater, and a transport portion configured to transport the aerosol source from the container to a heating area by the heater, the controller comprising

• a control circuit configured to monitor a voltage at a first terminal of the heater and configured to control power to be supplied to the atomizer such that the voltage at the first terminal under monitoring approaches a target value, the control circuit including
• an operational amplifier including a noninverting input terminal connected to a first terminal of the heater, and an inverting input terminal connected to a second terminal of the heater;
• and
• a microcontroller configured to compare an output of the operational amplifier, which is converted into a digital form, with the target value stored in a digital form in a memory to monitor the output of the operational amplifier as the voltage at the first terminal of the heater,
• wherein the target value is set such that a temperature of the heater during heating of the aerosol source falls within a range of 210° C. to 230° C.
