【 摘 要 】

The application of techniques of automation and control in greenhouses began in the years 50, starting with the control of temperature through thermostats. Since then, technological changes have covered all aspects that make up the system, from constructional features up to aspects of sustainability. The control of parameters sulh as, temperature and relative humidity, solar radiation, the concentration of CO2, ventilation and fertigation, had significant development, from which it provides a review of published works about these themes in recent years. Currently, issues related to reducing the impact to the environment and efficient production and quality, are taking the greenhouses towards Precision Agriculture.
