Abstract—Crop management depends on having the right information to make necessary decisions. Real-time monitoring of the greenhouse environment with sensors and advanced software can greatly improve yields and economic performance by optimizing plant growth. In this paper, we propose a system that can collect the information related to greenhouse environment and crop status and control the greenhouse automatically based on the collected information to predict and act on situations for perfectly controlled climatic conditions. By densely monitoring climatic conditions, this research has the purpose of establishing correlation between sensors signals and reference measurements, analyzing the growth, development of crops and the environmental variables to which they are exposed, to develop an automated computerized monitoring system for an intensive greenhouse facility that provides adequate control regardless of plant type or specie, and using this information to help farmers to increase yield, improve quality and timeliness of crops. Computer control software of LabWindows/CVI will provide data acquisition and control, real-time graphical display, dates and time tags the information and stores it for current or later use. Through long time running and practical using, the system has been proved that it has many advantages such as high testing precision, accuracy, and clear data management.

Index Terms—computerized monitoring, data acquisition, greenhouse environment, LabWindows/CVI, real-time monitoring, sensors.
