PLC-Based Smart Farm Control System

Product Overview

The MaaS UI 1.0-PLC is an integrated smart farm control panel designed to connect hydroponic greenhouses with the MaaS UI AIaaS-API Cloud Platform. Built on an industrial PLC architecture, the system seamlessly integrates sensors, nutrient systems, environmental control equipment, and cloud-based AI services into a single intelligent control solution.

By continuously collecting real-time environmental and irrigation data, the system enables automated cultivation management, AI-driven yield prediction, and precision environmental control for maximum productivity.

Intelligent Environmental Monitoring

The system collects real-time data through three sensor node boxes, monitoring six critical environmental and nutrient parameters:

• Temperature
• Humidity
• CO₂ Concentration
• Solar Radiation (Insolation)
• EC (Electrical Conductivity)
• pH

In addition, the PLC records daily cumulative irrigation volume and irrigation frequency through the integrated nutrient solution and flow meter system.

Smart Irrigation & Equipment Control

The PLC panel automatically controls various greenhouse devices using Modbus RS485 communication and industrial I/O modules.

The system supports:

• Nutrient solution system integration
• Flow meter monitoring
• Automatic irrigation control
• Irrigation frequency management
• 8 Window Openers
• 10 Air Circulation Fans
• 2 Exhaust Ventilation Fans
• DC Relay Switch Control
• Modbus Inverter Communication

This enables precise environmental management while minimizing labor and operating costs.

PLC & HMI Integrated Architecture

The control panel incorporates industrial-grade PLC modules together with an intuitive HMI touch panel.

The integrated system includes:

• Industrial PLC Controller
• Touch Panel HMI
• Internet Router
• Mini-PC
• Hub Switch
• Sensor Network
• Nutrient Solution Controller

All field devices communicate through a centralized PLC system for stable and reliable operation.

AI Cloud Connectivity

The MaaS UI 1.0-PLC communicates directly with the AIaaS-API Cloud Server, enabling continuous synchronization between greenhouse equipment and cloud-based AI services.

The cloud platform provides:

• Real-Time Monitoring
• Remote Equipment Control
• Environmental Data Management
• AI Yield Prediction
• Automatic Cultivation Recommendations
• Production Data Analysis

Precision Agriculture with AI
