1. An electronic device comprising:
a ring-type housing;
a motion sensor;
optical sensors disposed on one surface of the housing so as to be brought into contact with a finger of a user when the electronic device is worn by the user, wherein each of the optical sensors comprises a respective light emitter and a respective light receiver;
a sensor controller configured to control the optical sensors; and
a processor operatively connected to the motion sensor and the sensor controller,
wherein the processor is configured to:
when the electronic device is worn by the user, determine respective signal characteristics of the optical sensors by separately driving the optical sensors at different timings through the sensor controller;
determine a current state of the user from among a normal state, a sleep state, and an exercise state, based on at least one signal received through the motion sensor or the optical sensors;
determine at least one of the optical sensors to be driven based on the respective signal characteristics and the current state;
drive a light emitter of each of the at least one of the optical sensors through the sensor controller; and
select and receive, based on the respective signal characteristics of the optical sensors, a light signal sensed through a light receiver of the determined at least one of the optical sensors.
