Abstract
An electronic device according to various embodiments of the present invention may comprise: at least one electrode having conductivity; a capacitance sensor, at least one switch electrically connected between the at least one electrode and the capacitance sensor, and capable of selectively connecting the at least one electrode and the capacitance sensor; and a control circuit, wherein the control circuit measures a first capacitance value by using the capacitance sensor in a state where the at least one switch is open, measures a second capacitance value corresponding to an external object contacting the at least one electrode, by using the capacitance sensor in a state where the at least one switch is connected, corrects the second capacitance value by using the first capacitance value, and determines the corrected second capacitance value as a capacitance value for the external object. Various other embodiments are possible.
