Abstract

In this paper, we designed a smart home system that can be used intuitively and easily in everyday life, such as sending text messages to users, providing various information and scheduling using smart AI, and providing lighting and atmosphere suitable for the atmosphere in situations such as listening to music using neopixels, as well as using ESP32, RFID, and Google Cloude Console using raspberry pie. As a result of the experiment, it was confirmed that security characters were normally sent to users when RFID was recognized on ESP32 connected to Wi-Fi even if the power was reconnected, and smart AI using Neopixel lighting, Raspberry Pie, and voice recognition, which calculated frequency, also changed the recognition rate over distance, but it worked.

본 논문에서는 사람들의 안전하고, 편리한 생활을 위한 스마트 홈을 목표로 ESP32와 RFID, 라즈베리 파이를 이용한 구글 클라우드, 네오픽셀 등을 이용해 문이 열림과 동시에 사용자에게 문자 메시지 전송, 스마트 AI를 이용한 다양한 정보제공 및 일정관리, 네오픽셀을 이용하여 음악 감상 등의 상황에서 분위기에 맞는 조명의 밝기 및 분위기의 제공같이 직관적이고 일상생활에서 간편한 활용이 가능한 스마트 홈 시스템을 설계하였다. 실험결과 전원이 재 연결 되도 Wi-Fi와 연결된 ESP32에서 RFID가 인식될 때 보안문자가 정상적으로 사용자에게 전송되는 것을 확인하였고, 주파수를 계산한 네오픽셀의 조명 및 라즈베리파이와 음성인식을 이용한 스마트 AI또한 거리에 따라 인식률의 변화가 있지만 작동됨을 확인하였다.
