Greenhouse Electrical Control Cabinet: The Core of Intelligent Management
In modern greenhouse engineering, the serves as the "brain" of the greenhouse automation system, playing a crucial role. It not only precisely regulates environmental parameters but also integrates with IoT (Internet of Things) technology to enable remote monitoring and intelligent management. This article explores the functions, applications, and key roles of the electrical control cabinet in polypropylene greenhouses, greenhouse sunshade systems, motorized exterior sun shades, greenhouse fans, and other critical components.

1. Core Functions of the Greenhouse Electrical Control Cabinet
The central unit for greenhouse climate regulation, with key functions including:
Environmental monitoring – Collects real-time data on temperature, humidity, light intensity, and CO₂ levels inside and outside the greenhouse.
Automated equipment control – Adjusts greenhouse fans, evaporative cooling pads, heating systems, and grow lights automatically or manually to maintain optimal growing conditions.
Energy efficiency optimization – Analyzes data to optimize equipment operation and reduce power consumption.
Remote management – Connects to IoT platforms, allowing users to monitor and adjust greenhouse settings via smartphones or computers.
2. Applications of Electrical Control Cabinets in Greenhouse Engineering
(1) Climate Control in Polypropylene Greenhouses
Polypropylene greenhouses are widely used due to their excellent light transmission and weather resistance. However, their internal climate is highly susceptible to external weather changes. The electrical control cabinet connects to sensors and actuators to automatically regulate ventilation, shading, and humidity, ensuring ideal growing conditions.
(2) Smart Management of Greenhouse Sunshade Systems
Greenhouse sunshade systems are essential for controlling light intensity, especially during hot summers. The electrical control cabinet automates motorized exterior sun shades, adjusting shading levels based on light sensor data to prevent crop sunburn while ensuring sufficient photosynthesis.

(3) Efficient Operation of Greenhouse Fans & Ventilation Systems
Greenhouse fans are critical for temperature and humidity control. The electrical control cabinet activates or deactivates fans based on sensor feedback, working alongside evaporative cooling systems for efficient temperature reduction. It can also integrate with CO₂ sensors to optimize airflow and enhance plant growth.
(4) Integration with IoT Technology
Modern greenhouse engineering is evolving toward smart automation. The electrical control cabinet, when connected to IoT via 4G/5G or Wi-Fi, enables:
Remote monitoring – Growers can check real-time greenhouse conditions via mobile apps.
Data analytics – The system logs historical data and generates reports to improve cultivation strategies.
Alerts & notifications – Sends warnings for high temperatures, low humidity, or equipment failures to minimize crop loss.
3. Key Technologies in Electrical Control Cabinets
(1) PLC (Programmable Logic Controller)
The PLC is the core component of the electrical control cabinet, handling logic operations and equipment control. Its reliability and programmability make it suitable for greenhouses of all sizes.
(2) Sensor Networks
Temperature & humidity sensors – Monitor internal climate.
Light sensors – Adjust motorized exterior sun shades and supplemental lighting.
CO₂ sensors – Optimize ventilation for higher crop yields.
(3) Human-Machine Interface (HMI)
Modern electrical control cabinets often feature touchscreen interfaces for easy parameter adjustments and system monitoring.
(4) IoT Connectivity
Wireless communication modules allow the electrical control cabinet to sync with cloud platforms for big data analysis and remote management.
4. Selecting & Maintaining an Electrical Control Cabinet
(1) Selection Guide
Small greenhouses – Basic control cabinets for managing greenhouse fans and sunshades.
