Humidity Balance Optimization with Circulation Fan Control in Greenhouse Automation

In modern greenhouse cultivation, the most fundamental requirement for obtaining high yield and quality products is to provide a homogeneous climatic environment suitable for the needs of the plants. One of the most critical elements in providing this controlled environment is circulation fans. Circulation fans manage not only the temperature but also the humidity and carbon dioxide (CO₂) balance within the greenhouse. This process, which is managed manually in traditional greenhouses, has become completely controllable by sensors thanks to Esular’s smart automation systems.

In this article, we will examine in detail the role of circulation fans in greenhouse climate control, why humidity balance is vital, and how Esular optimizes these systems with wireless sensors. Additionally, we will touch upon automatic window control solutions, which are an integral part of fan systems.

Esular Wireless CO2, Humidity and Temperature Sensor

The Critical Role of Circulation Fans in Greenhouse Climate

Circulation fans, which continuously move the air flow inside the greenhouse, perform several basic functions:

1. Humidity Balance and Prevention of Fungal Diseases

Plants release water vapor from their leaf surfaces as part of their natural processes (transpiration). In a greenhouse, which is an enclosed environment, this water vapor can condense on leaf surfaces and turn into water droplets. **However**, this situation creates an ideal environment for the spread of fungal diseases such as fungi and mold. Circulation fans prevent this condensation and protect plant health by continuously removing the saturated air layer on the plant surface. At the same time, they help in the homogeneous distribution of the humidity created by fogging systems.

2. Temperature and CO₂ Homogenization

When heating systems are used, warm air accumulates at the top, while the floor remains cold. Similarly, as plants consume CO₂ during photosynthesis, the CO₂ level around the leaves decreases. **On the other hand**, circulation fans ensure a homogeneous temperature and CO₂ distribution within the greenhouse by continuously mixing these air layers. This homogeneity is of critical importance for plant development.

Esular Smart Fan and Window Control: Integrated Automation

While traditional fan control is done with a simple thermostat or timer, the Esular system decides in real-time when and in which position the fans and ventilation windows should operate via precise wireless sensors. This integrated approach provides maximum efficiency and energy savings.

Perfect Integration with Window Control

Fans alone are not sufficient to meet ventilation needs; they must work in integration with the automatic window control system. The central control unit adjusts the window position primarily to optimize ventilation. For example, when humidity rises, the windows open automatically.

External factors such as wind speed and precipitation are continuously monitored with Esular meteorology station data. If the wind speed is high, the windows are closed and the air inside is moved with fans. **Furthermore**, when the CO₂ level drops, the windows are automatically brought to the appropriate position for fresh air intake. This smart scenario completely eliminates the need for manual intervention.

Esular Integrated Climate Management Products

To manage fan and window systems from a single center, examine Esular's wireless and smart product family:
