1. A method of measuring biometric information in a sensor node including a controller for driving a sensor to measure the biometric information, the method of measuring the biometric information comprising steps of:

  • detecting a movement of a living body by a first sensor for detecting the movement of the living body when power is supplied from a battery to the first sensor by the controller;

    determining whether or not measurement by the second sensor is possible based on the detected movement of the living body by the controller; and

    shutting off power to the first sensor having a power consumption lower than that of the second sensor when the determination results show that measurement is possible, and supplying power to the second sensor having a power consumption larger than that of the first sensor to measure the biometric information.
