The Feasibility of a Cloud-Based Low-Cost Environmental Monitoring System Via Open Source Hardware in Greenhouses

One of the most critical parameters in agricultural production isenvironmental conditions. It is of vital importance to ensure andmonitor suitable climatic conditions for various controlled agriculturalstructures and production systems such as greenhouses. To this aim,most data monitoring systems cannot be efficiently used due to highcost and insufficient technical knowledge. It is possible to design lowcostand scalable monitoring, control and data acquisition systems viaopen source hardware in order to monitor climatic data foragricultural practices in small enterprises and rural areas. In thisstudy, a low-cost system designed via open source hardware wastested under real conditions. Temperature and relative humidity weremeasured via the sensors in the system and sent to a data serverthrough a wireless network. In addition, collected data was comparedto reference devices for statistical analysis. The results suggest thatthese low-cost systems, which are designed via open source hardware,can be used as a data collection and decision support system byagricultural enterprises.

Açık Kaynaklı Donanım ile Bulut Tabanlı ve Düşük Maliyetli Bir Çevre Koşulları İzleme Sisteminin Seralarda Uygulanabilirliği

Tarımsal üretimi etkileyen en önemli parametre çevre koşullarıdır. Uygun iklim koşullarının sağlanması ve bu koşulların takip edilmesi özellikle kontrollü üretim yapıları olan seralar başta olmak üzere birçok tarımsal yapılarda ve üretim sistemlerinde hayati önem arz etmektedir. Bu amaçla kullanılan birçok veri izleme sistemi, yüksek maliyet ve yeterli teknik bilgi olmadığından yaygın bir şekilde kullanılamamaktadır. Özellikle küçük işletmelerde ve kırsal bölgelerde, tarımsal faaliyetler için hayati öneme sahip iklim verilerinin izlenmesi amacıyla, açık kaynak donanımlar ile düşük maliyetli ve ölçeklenebilir izleme, kontrol ve veri toplama sistemleri tasarlanması mümkün olabilmektedir. Bu çalışmada açık kaynak donanımlarla düşük maliyetle tasarlanan sistem, gerçek koşullarda test edilmiştir. Tasarlanan bu sistemde sıcaklık ve oransal nem değerleri sensörler ile ölçülerek kablosuz bir ağ üzerinden veri sunucusuna aktarılmıştır. Ayrıca bu veriler referans cihazlarla karşılaştırılarak istatistiksel olarak değerlendirilmiştir. Elde edilen sonuçlar, açık kaynak donanımlar ile tasarlanan düşük maliyetli bu tür sistemlerin tarımsal işletmelerde veri toplama-izleme ve karar destek sistemi olarak kullanılabileceği göstermiştir.
