Cultivation in agricultural greenhouses without adequate monitoring, depending on theuncontrolled climate, makes it impossible for the farmer to produce certain foods adequately. Based on this, the DIANA (Agricultural Greenhouse Analysis and Control Device) research project was developed. "The ability to control the internal environment of the greenhouse makes the results better than those achieved in the open field. "(JUNIOR;2015, UFSC). That said, it is through climate analysis and control that the best results in crops are obtained. The DIANA device aims to provide the user with a systemelectronic that acts in the search to guarantee the ideal climatic conditions for the production in greenhouses of horticultural products; because it simulates a desired microclimate inside a greenhouse. the user will be able to select the values of humidity, temperature and luminosity that he desires in the central of the equipment. Once the desired data has been selected, the system will automatically act in order to control it using electric actuators. This will provide the farmer and the population with a better quality product.
