University Students Invented 'Remote Control System for the Greenhouses'

Three students from KTÜ Electrical and Electronic Engineering offer one system including many functions in greenhouse with "Smart irrigation system with remote tracking of moisture and heat of the soil in greenhouse" they designed.

Three students from Karadeniz Technical University (KTÜ) Electrical and Electronic Engineering offer one system including many functions in greenhouse with "Smart irrigation system with remote tracking of moisture and heat of the soil in greenhouse" they designed.

Under the supervision of the project coordinator Asst. Prof. Dr. Hakan Kahveci, senior students Mert Kolukırık, Ertuğrul Ustaömer, and Bilge Nur Taşdelen designed a system as their thesis, which provides the producers an opportunity to do greenhouse work only in October and harvest time, contributes to product efficiency, and enables pesticide-free production.

The project manager Kolukırık spoke to an AA reporter and explained that suitable climatic conditions for the growth and flourishing of the greenhouse plants would be ensured by controlling variables such as the heat, relative humidity, and solar radiation.

Stating that the desired climatic conditions inside the greenhouse are constantly changing because of the outside factors such as the sun, heat, and the rain, Kolukırık noted that the system they had designed in this context had fully automatic operation.

Pointing out that the system they have designed allows for irrigation and air conditioning, Kolukırık added: "Smart irrigation is made according to the moisture data of the soil. If the soil moisture is under the desirable level, our irrigation system works and we give ozonized water to the soil. Giving ozonized water to the soil, our aim is to maximize the relationship of nitrogen and the soil minerals, and grow crops much more efficiently. It also allows for air conditioning. If the greenhouse is too hot or the heat is above the desirable level, our ventilation system kicks in. After the ventilation system disengages, we ozonize the environment via ozone generator, as the innovative element of the system."

"We have developed such a system to grow every crop in everywhere."
Emphasizing that ozonizing the environment is aimed at eliminating harmful parasites, microorganisms, and insects without using pesticides, Kolukırık noted: "In this way, we avoid using pesticides and create a much more efficient environment for the plants and crops. Besides, if the greenhouse environment is too cold, the heat is under a certain level, which we decided 10 degrees, our heating system engages. Apart from this, we have lighting system. When the weather is dark, plants might slow down photosynthesis, and we have installed a lighting system and blue led to prevent this from happening and to accelerate the growth of crops."

Stating that the lighting system runs on blue leds, Kolukırık added: "We also have a shadowing system to prevent overheating in the greenhouse especially in the summer, when the sun's rays reach Earth at very high ankles at noon between 12 and 4 p.m. Through this system, we prevent the negative effects of sun's rays. So that we prevent overheating in the greenhouse."
