MONITORING SYSTEM OF PHYSIOLOGICAL PHEONOMENA USING USN AND MULTIPLE SENSORS

摘要

PURPOSE: A physiological phenomenon monitoring system based on USN(Ubiquitous Sensor Network) and multi sensor is provided to predict a gas exhaustion from human body by comparing a measuring value of temperature and humidity with a previous value. CONSTITUTION: A temperature sensor(121) is installed inside a physiological phenomenon influence region of a subject in order to measure a temperature. A humidity sensor(122) is installed inside the physiological phenomenon influence region of the subject in order to measure humidity. A gas sensor(123,124) is installed inside the physiological phenomenon influence of the subject in order to detect a methane gas or an ammonia gas. An MCU(Microcontroller Unit)(111) classifies feces and urine by comparing the temperature and the humidity measured by the temperature sensor and the humidity sensor with previous values. A local area wireless communication part(112) transmits a message received from the MCU to a local area wireless communication network.
