Capabilities of microclimate parameters control with the use of embedded system

Abstract

The paper describes a practical application of an embedded system for controlling selected microclimate parameters. The microclimate control system was designed, performed and programmed. The study was preceded by an analysis of a possibility of growing plants in artificial climatic conditions. An effect of light energy on a plant growth and types of electric light sources were presented. The aificial light sources used in crops of useful plants under opaque shields were used: light source technologies were analyzed and compared in terms of an optimal lighting efficiency, durability and spectral composition of radiation. The control system is described: it consists of a control unit and controlled components. A software is designed for microcontroller, which controls individual elements of the system. A block diagram of the system was shown. In order to verify the correct functioning of the system, an experiment confirming a correct and progressive growth and development of the selected plants were performed.
