Abstract

In this study, we developed an IoT-based management system to manage a can/PET crusher. Various sensors such as two load cells, DHT22 temperature and humidity sensor, and fine dust meter were interfaced with ESP32 to construct an IoT device, and a management server was built using Node-RED. The system monitors the weight of pressed cans and shredded PET bottles in real time and sends a text message to the manager when the weight exceeds the predetermined threshold for timely collection. The results of the operational test confirmed that the system provides accurate monitoring and efficient notification functions, and offers the possibility of solving environmental problems by improving the efficiency of waste management such as cans and PET bottles.

본 연구에서는 캔/PET병 압착파쇄기를 관리하기 위한 IoT 기반의 관리시스템을 개발하였다. 로드셀 2개, 온습도센서 DHT22, 미세먼지 지측정기 등 다양한 센서를 ESP32와 인터페이스하여 IoT 디바이스를 구성하였으며, Node-RED를 활용하여 관리 서버를 구축하였다. 본 시스템은 압착캔과 파쇄된 PET병의 무게를 실시간으로 모니터링하고, 미리 정한 기준치를 초과할 경우 관리자에게 문자 메시지를 전송하여 적시에 수거할 수 있도록 하였다. 운영 시험 결과 본 시스템은 정확한 모니터링과 효율적인 알림 기능을 제공함을 확인하였으며 캔/PET병 과 같은 폐기물 관리의 효율성을 제고하여 환경 문제를 해결할 수 있는 가능성을 제시하였다.
