Controller for sensor node, measurement method for biometric information and its software |
摘要 |
The precision of measuring biometric information is enhanced while suppressing the consumption of a battery in a sensor node. In a method of measuring the biometric information in a sensor node including a controller for driving a sensor to measure biometric information, the controller supplies power from a 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 (P 330 ), 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 supplying power to the pulsebeat sensor having a power consumption larger than that of the acceleration sensor to measure the biometric information (P 340 ).
