1. Heart rate monitor device for monitoring a heart rate of a user, comprising:

  • at least one primary sensor for measuring a heart rate of user, wherein the at least one primary sensor has a first power consumption,at least one secondary sensor for measuring at least one physiological factor influencing the heart rate of a user, wherein the at least one secondary sensor has a second power consumption which is lower than the first power consumption,a power management unit for managing an operation of the at least one primary sensor based on information received from the at least one secondary sensor,a model unit for estimating the heart rate of a user based on a model stored in the model unit and the information received from the at least one secondary sensor, wherein the model unit is coupled to the power management unit via a feedback loop such that the power management unit is adapted to decrease a sampling frequency and/or measurement intensity of the primary sensor if the estimated heart rate and the measured heart rate correspond to each other.
