    Population groups sensitive to pollutants need to be managed when they are exposed to indoor air pollution. This study is aimed at identifying characteristics of environmental hazards within households using IoT-based environmental measurement. Environmental measurement was conducted in homes and offices, where data about volatile organic compounds (VOCs), PM1.0, PM2.5, PM10, CO2, temperature, and humidity were collected from September to December 2017. The IoT-based measurement was made for 24 hours and classified according to times of the day. It was reported that the concentration of fine dust increased during family gatherings, especially in the evening (18:00-24:00). CO2 and VOCs showed increasing concentrations from 18:00 pm to dawn. In this study, it was shown that the increase in indoor air pollutants at homes was related to the lifestyle of family members.
