A biological information measuring apparatus includes a sensing device and a calibration device. The calibration device includes a transmitter transmitting, to the sensing device, data including the first biological information, and calibration identification information. The sensing device includes a determination unit determining whether the calibration identification information is information of a calibration device corresponding to the sensing device； a detector detecting a pulse wave； and a calculator, when the calibration identification information is information of a corresponding calibration device, calibrating the pulse wave based on the first biological information, and calculating second biological information based on the calibrated pulse wave.
