Method and system for processing sensor data

A method and system for processing sensor data is provided to estimate a state grade in future after determining the state grade at current time by corresponding the state of space to time information through a sensor data analysis. A sensor data processing system(200) is comprised of sensor data identification means(210), state grade decision means(220), and the condition grade prediction means(230) and apparatus for transmission message(240). A space for the sensor network is determined based on the object space storage(250) the reference. The apparatus for transmission message provides the alerting message about the condition grade at the condition grade at the moment when being determined or the future time point when being predicted.
