Abstract

As the demand for healthy food increases, an automated system capable of precisely controlling the growth environment is essential for stable crop production. This study proposes an automated system for monitoring and controlling plant factories. It manages the growth environment using Arduino and various sensors, utilizing an efficient air circulation method to maintain stable internal temperatures. The experiment showed that the proposed system maintained a temperature deviation of ±1℃, a pH of 6.0, and an electrical conductivity of 1.6 dS/m, meeting standard performance. Additionally, leaf growth was found to be superior compared to crops grown in open-field conditions. The proposed system is expected to help reduce labor costs and improve the efficiency of cultivating high-quality crops.

기후 변화와 환경 오염으로 인해 건강한 먹거리에 대한 수요가 증가하면서 육묘산업의 발전이 요구되고 있으나, 인구 고령화로 인한 기술 인력이 부족해지면서 작물의 생산과 관리가 어려워지고 있다. 이에 따라, 자동화된 작물 생육 시스템의 필요성이 높아지고 있으며, 고품질 작물의 안정적인 생산을 위해서는 모종의 생육 환경을 세밀하게 조절하는 것이 필수적이다. 본 연구에서는 식물공장 내부 환경을 모니터링하고 조절할 수 있는 자동화 제어시스템을 제안한다. 제안하는 시스템은 아두이노 및 다양한 센서를 통해 온도, 습도, 광량, 양액 공급을 관리하며, 고효율의 공기 순환 방식으로 내부 온도의 변동을 최소화한다. 로메인 상추를 대상으로 실험을 진행한 결과, 제안하는 시스템은 온도 편차 ±1℃, pH 6.0, 전기 전도도 1.6 dS/m으로 식물공장 표준 성능에 부합하였으며, 노지 환경에서 재배된 작물보다 잎의 성장이 우수함을 확인하였다. 제안된 시스템은 노동 비용의 절감과 고품질 작물의 재배 효율성 향상에 도움을 줄 수 있을 것으로 기대된다.
