AEROSOL GENERATION DEVICE PROVIDED WITH CONTROL UNIT FOR DETECTION OF ABNORMAL STATE OF SENSOR

A power supply unit of an aerosol generation device that supplies electric power to a load that generates aerosol including a sensor that is in an operating state among a normal state and a plurality of abnormal states, and detects an aerosol generation request while the power supply unit is in an active state, a control unit that detects a state of the sensor, and generates an error signal capable of distinguishing between a first and second abnormal states when the sensor is in at least one of the first and second abnormal states included in the plurality of abnormal states, and a notification unit that makes a notification in a different mode for each type of the error signal, wherein the control unit causes the power supply unit to undergo a transition from the active state to a sleep state after generating the error signal, and the plurality of abnormal states include a state in which supply of electric power to the load is unnecessary for detection by the control unit.
