1. A controller for a sensor node to be worn by a living body, comprising:

  • a controller for measuring biometric information by driving a sensor;

    a radio communication circuit for transmitting the biometric information obtained by the controller; and

    a battery for supplying power to the controller, the radio communication circuit, and the sensor, wherein the sensor comprises a first sensor for detecting a movement of the living body, and a second sensor for measuring the biometric information, wherein the controller comprises a measurement start determination part for supplying power from the battery to the first sensor to detect the movement of the living body and determining whether or not measurement by the second sensor is possible based on the movement of the living body, and a biometric information measurement part for starting a supply of the power to the second sensor to measure the biometric information after shutting off the power to the first sensor when determination results of the measurement start determination part show that measurement is possible, and wherein a power consumption of the first sensor is lower than a power consumption of the second sensor.
