사물인터넷 기반 실내환경 측정 센서 모듈 개발

Abstract

The purpose of the study is to develop an IoT sensor module for environmental measurement that can compare indoor and outdoor contamination. Low-cost and high-performance indoor environmental devices have been developed for easy access by researchers. The results as follows: The products used the Aduino Uno R3 with outstanding scalability and affordability. Performance verification shows the same trend of Fine dust concentration, Temperature and humidity error rate were 4.08% and 4.96% respectively, Air flow error rate is 4.58%. Therefore, the sensor modules developed in this study can be applied indoor the building for environmental measurement and are easily accessible to other researchers.
