Abstract: An electronic device and a method for controlling the electronic device are provided. The electronic device includes a motion sensor and optical sensors. Each of the optical sensors includes a light emitter and a light receiver. The optical sensors are separately driven to determine a respective signal characteristic of each of the optical sensors. A current state of an object to be measured is determined, based on at least one signal received through the motion sensor or the optical sensors. A light emitter of at least one of the optical sensors is driven, based on the respective signal characteristics of the optical sensors according to the current state of the object to be measured. Based on the respective signal characteristics of the optical sensors, a light signal sensed through a light receiver of at least one of the optical sensors is selected and received.

Abstract: An electronic device may include at least one sensor, a communication circuit, and at least one processor operatively connected with the at least one sensor and the communication circuit. The at least one processor may be configured to: if change amount of movement of the electronic device obtained via the at least one sensor is within a threshold range, identify a wearing state of the electronic device via the at least one sensor, select a group which corresponds to the wearing state from among a plurality of groups including a first group including saturations of percutaneous oxygen (SpO2s) which may correspond to reference values based on photoplethysmogram (PPG) signals and a second group including other SpO2s which may correspond to the reference values, and obtain a first PPG signal via the at least one sensor, and obtain a first SpO2 using the selected group and a first reference value which is based on the first PPG signal. Other embodiments are possible.
