초록

하루 평균 90%를 실내에서 생활하는 현대인들을 위해 온도, 습도, 미세먼지 등을 제어하여 쾌적한 실내 환경으로 제어해 주는 시스템이다. 불쾌지수가 온도와 습도 중 영향이 큰 성분을 찾는 실험에서는 온도를 21도로 고정 했을 시 습도가 1% 변하는 경우 불쾌지수 0.1이 증가하였고 습도를 40%로 고정하고 온도가 1도 변할시 불쾌지수가 1.2씩 변하는 실험결과를 도출하였다. 이로부터 온도가 영향력이 크다는 것을 알아냈다. LED 실내등과 릴레이 소켓을 메인 제어 시스템에 무선통신을 사용하기 위한 블루투스의 통신한계 측정실험에서 장애물이 없을 시 최대 70m 통신 가능 했으며 벽이나 철근과 같은 고분자 장애물이 있는 경우 통과하여 통시할 수 있는 장애물이 최대 2개였고, 고분자 장애물 하나를 사이에 두고 통신 할 수 있는 거리는 최대 10m임을 확인하였다.

It is a system that controls temperature, humidity and fine-dust to make interior environment more comfortable for modern people who spend 90% of the time in indoor. In an experiment of finding which one of temperature and humidity influence more to discomfort index, for a fixed temperature of 21, discomfort index increased by 0.1 with a 1 change of humidity, and for a fixed humidity of 40, discomfort index increased by 1.2 with a 1 change of temperature. As a result, it was found that the temperature is more influential than the humidity to discomfort index. In an experiment of measuring communicational limitation of Bluetooth, the communication was possible for at most 30 meters without obstacles. With high obstacles like walls or steel bars, it was able to penetrate at most 2 obstacles and maximum distance which it can communicate was 10 meters for just one high molecule obstacle.
