A pulse measurement device for more precisely measuring a pulse, including a sensing unit to sense a photoplethysmography (PPG) signal and an acceleration signal obtained from a user, a pressure control unit to control pressure applied to the sensing unit, and a signal determination unit to determine an optimum pressure range by analyzing the PPG signal varying with a change of the pressure applied to the sensing unit by the pressure control unit and to determine an exercise level of the user by using the acceleration signal.
