Production in greenhouses is a technique that aims at protecting flowers and vegetable production against meteorological agents that affect production adversely, as well as allowing favorable environments throughout the year with productive and commercial advantages. One important issue regarding greenhouse systems is the control of the air temperature and relative humidity. The automatic environmental control allows the improvement of quality, and the efficient and rational use of resources. The aim of this work was to develop a system of temperature and humidity control for a greenhouse prototype in reduced scale, by using the concepts of Fuzzy Logic. The input variables were: air temperature and humidity, and the output variables were: changes in the environmental heating system and humidification. The environmental control was simulated and project parameters were adjusted. The results of the simulation showed that the air temperature and humidity adjustment based on the inference developed Fuzzy system, was satisfactory for the performance of the greenhouse environmental control.
