Abstract: An electronic device is disclosed. According to an embodiment disclosed herein, an electronic device may include a PPG sensor including a light emitter that applies a current in a specified range and emits a light signal corresponding to the current and a light detector that amplifies a received light signal by applying one of a plurality of gain values, a memory that stores a plurality of sets of PPG models corresponding to the plurality of gain values and including a current value and PPG level data corresponding to the current value, and at least one processor electrically connected to the PPG sensor and the memory, wherein the at least one processor may acquire a first PPG signal from the PPG sensor set with a first current value satisfying the specified range and a first gain value of the plurality of gain values when a user's contact is detected by the PPG sensor, generate a first PPG model corresponding to the user based on a first PPG model set corresponding to the first gain value among the plurality of sets of PPG models, the first current value and the first PPG signal, determine a second gain value and a second current value for acquiring a PPG signal with a specified PPG level, based at least on the first PPG model set, and acquire a second PPG signal with the specified PPG level using the PPG sensor set with the second gain value and the second current value. In addition, various embodiments understood from the specification are possible.

Abstract: Disclosed is an electronic device including a detection circuit and a processor operatively connected to the detection circuit. The processor is configured to obtain a first signal associated with an external object through the detection circuit, to obtain a first HR, using a first filter having an attribute of a first frequency band and to obtain a second HR, using a second filter having an attribute of a second frequency band, based at least on the first signal, to change at least some attributes associated with the second filter, based at least on the first HR and the second HR, and to obtain a second signal associated with the external object through the detection circuit, and generate heart rate variability (HRV) information, using the second filter, in which the at least some attributes are changed, based on the second signal. In addition, various embodiments as understood from the specification are also possible.
