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.
