EXTERNAL UNIT FOR INHALATION COMPONENT GENERATION DEVICE, INHALATION COMPONENT GENERATION SYSTEM, METHOD FOR CONTROLLING EXTERNAL UNIT FOR INHALATION COMPONENT GENERATION DEVICE, AND NON-TRANSITORY COMPUTER READABLE MEDIUM

An external unit for an inhalation component generation device includes a connection part that is electrically connectable to a power supply unit of the inhalation component generation device, a sensor that is capable of outputting an output value related to an electrical resistance value of a resistor provided in the power supply unit, and a first control part that is configured to determine, based on the output value, whether to change a predetermined control with respect to the power supply unit connected to the connection part or whether to perform the predetermined control.
