Keywords : Asthma, Atopy, Indoor air pollutants, IoT(Internet of Things), Childhood Abstract :Background: Indoor air pollutants have been regulated since 1980 and the importance of indoor pollutants is increasing. Asthma and atopy are known to be infant and childhood diseases. According to the data of National Health Insurance Corporation, 43.2% of asthmatic patients are children under 12 years of age, and atopic dermatitis is high as half of patients and it is more necessary to study asthma in children. Methods: The subjects were (1) home environment measurement of allergic patients and (2) indoor air quality according to interior decoration. In this study, IoT indoor air quality equipment was installed at 3 years of national public nursing homes, 1 day nursery, 3 day nurseries and 2 years old (4 years old). From May 2018 to April 2019, we will carry out measurements for ultra-fine dust, ultrafine dust, fine dust, CO2, VOCs, and temperature and humidity. The data of the measurement is confirmed in real time, and it is downloaded from the central center for analysis.Results: A total of 63,928 data were collected for 5 months, 32,019 in the experimental group and 31,909 in the control group In VOCs, the average concentration of experimental group was 145.80 ãŽ/㎥ and the average concentration of control group was 145.20 ãŽ/㎥. In CO2, the average concentration value of the experimental group was 681.00 ppm and the average concentration value of the control group was 782.40 ppm. In HCHO, the average concentration value of experimental group was 81.87 ãŽ/㎥ and the mean concentration value of control group was 65.85 ãŽ/㎥.Conclusions: It is known that fine dusts and chemical harmful substances in the indoor air have a high correlation with allergies such as asthma and aggravation of symptoms of asthmatic patients. As a part of the project to create a dust free environment, IoT-based real-time indoor air quality measurement system was used to collect data. There was a difference in the average concentration value between the experimental group and the control group, and the concentration was higher in the nursery built within the last 1 year. According to recent data, KT recently released open IoT platform collects and analyzes air quality data in 1 minute increments.
