Abstract: An electronic device is provided. The electronic device includes a housing, light emitting diodes (LEDs) of a first number, photodetectors of a second number, and a control circuit operatively connected to the LEDs and the photodetectors. The control circuit is configured to cause the LEDs of a third number to emit light sequentially or simultaneously and to cause the photodetectors of a fourth number to detect light from the LEDs of the third number. The third number is 1 or 2. The fourth number is one of an integer that is not less than 2 and is not greater than the second number.

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 is provided. The electronic device includes a housing including a first surface, a second surface and a conductive frame disposed between the first surface and the second surface and including a through-hole, a first electrode is movable within the through-hole, a part of the first electrode protruding to outside of the conductive frame, a second electrode disposed on the second surface, and at least one processor. The at least one processor is configured to identify whether the first electrode is electrically disconnected to the conductive frame, obtain an information about the user' body through the first electrode and the second electrode, and refrain from obtaining the information based on identifying the first electrode is electrically connected to the conductive frame.
