摘要： PROBLEM TO BE SOLVED: To improve the precision of measuring biometric information while suppressing the consumption of a battery in a sensor node. SOLUTION: In a measuring method for biometric information in a sensor node including a controller for driving a sensor to measure biometric information, the controller supplies power from the battery to an acceleration sensor for detecting the movement of a living body to detect the movement of the living body. The controller determines whether or not measurement by a pulsebeat sensor is possible based on the detected movement of the living body (P330), and shuts off power to the acceleration sensor having a power consumption lower than that of the pulsebeat sensor when the determination results show that measurement is possible, and thereafter supplies power to the pulsebeat sensor having a power consumption larger than that of the acceleration sensor to measure the biometric information (P340).
