Projeto de um sistema automatizado para estufa de morangos com CLP e IHM

Abstract

This paper presents the design and development of an intelligent automation system for an approximately 50 m x 10 m (500 m²) strawberry greenhouse related to ED Agrícola. The proposed solution uses a Siemens S7-1200 PLC, Unified HMI, industrial sensors, electromechanical actuators and remote supervision to control irrigation, ventilation, shading and supplemental lighting. The system includes four independent irrigation zones, environmental monitoring, pump protection by reservoir level, exhaust fan control, motorized curtains, shading screens and LED Grow lighting. The methodology included the survey of greenhouse requirements, control architecture definition, I/O mapping, functional diagrams, cost estimation and simple payback simulation. The expected results include reducing manual intervention, improving microclimate stability, optimizing water use and providing a safer and more standardized solution.
