Control and Monitoring of Greenhouse System with Matlab GUI

Abstract

One of the most effective solutions is to produce the obtained product all year round not only in spring and summer seasons which are suitable for producing the plant. Furthermore, conventional closed greenhouses are converted into high-tech plant production units in as much as micro controllers, smart sensors and wireless technology equipment have become cheaper and easily available in recent years. To this end, a low-cost greenhouse automation system which can be monitored in computer environment by virtue of an interface created in Matlab GUI programming language is proposed in the study. Temperature, air relative humidity and soil moisture levels were measured continuously as input and control of heating, ventilation, drip irrigation, humidification, and lighting system was conducted the way of on-off in the proposed system. Furthermore, input sizes were monitored graphically and numerically on the interface and output systems were monitored instantly to observe if they operated or not. Required conditions in the greenhouse for pepper and eggplant as vegetables and strawberry as fruit was provided and data for 24 hours were provided. The obtained numerical and visual application result revealed the fact that the applied system is more advantageous compared to conventional control systems in terms of ease of use, price, monitoring and simultaneous recording.
