1. An apparatus for estimating biological information, comprising:
a sensor configured to detect a first light signal and a second light signal that are reflected or scattered from a body part of a user; and
a processor configured to determine whether a condition for estimating the biological information is satisfied based on the first light signal, and in response to the biological information being satisfied, estimate the biological information based on the second light signal,
wherein the sensor comprises:
a cover surface configured to be in contact with the body part;
a first light emitter disposed on a first substrate and configured to emit a first light to the body part;
a second light emitter disposed on a second substrate and configured to emit a second light, the second substrate being disposed closer to the cover surface than to the first substrate;
a light detector configured to detect the first light signal from the first light that is emitted to and then scattered or reflected from the body part, and detect the second light signal from the second light that is emitted to and then scattered or reflected from the body part; and
a force sensor configured to measure a force applied to the body part when the body part is in contact with the cover surface, and
wherein the processor is further configured to provide a list of a plurality of different types of biological information to the user and control the second light emitter according to a driving condition of the second light emitter corresponding to a biological information type selected by the user from the list.
