PORTABLE ENVIRONMENTAL SENSOR MEASURING AND CORRECTING SYSTEM AND THE METHOD THEREOF

The present invention which relates to portable environmental sensor measuring and correcting system measuring harmful environmental pollution level by using an environmental sensor in which data is corrected and the method thereof, includes a system correcting unit for removing noise of an environmental sensor, correcting gradient difference according to measured sensing value based on air pollutant concentration value of the environmental sensor in which the noise is removed according to a correcting parameter, and correcting environmental sensor value according to temperature-humidity change which changes characteristics of the environmental sensor, a contamination measuring unit for displaying pollution status by measuring pollution level for the measured sensing value according to corrected value, and a baseline correcting unit for correcting error of the measured sensing value by using national measurement network data based on location information.
