Controller for senor node, measurement method for biometric information and its software
First Claim
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.

Abstract
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 (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 supplying power to the pulsebeat sensor having a power consumption larger than that of the acceleration sensor to measure the biometric information (P340).
