Abstract: Provided is an electronic device including a housing; a battery; a user interface; a photoplethysmogram (PPG) sensor including a light receiving module exposed through a portion of the housing, at least one light emitting diode (LED), and at least one photodiode; a processor operatively connected to the battery, the user interface, and the PPG sensor; and a memory. According to an embodiment, the memory stores instructions that, when executed, cause the processor to determine whether the PPG sensor is facing a surface of an external object having a reference color, determine whether to perform a test of the PPG sensor based on whether the PPG sensor is facing the surface, receive data from the PPG sensor by operating the PPG sensor in response to determining to perform the test, and perform calibration of the PPG sensor based on at least a portion of the received data. Other embodiments are possible.

Abstract: An electronic device for obtaining biological information and a method therefor are provided. The electronic device includes a biometric sensor module including a light emitting module including a first light emitting element having a first attribute and a second light emitting element having a second attribute and light receiving modules disposed adjacent to the light emitting modules, and at least one processor. The at least one processor is configured to determine a distance between the biometric sensor module and an external object based on at least reflected light reflected by collision with the external object among light output from the light emitting module, select at least one of the first light emitting element or the second light emitting element based on the distance, and obtain biometric information about the external object using the selected light emitting element.
