The main objective of this project is to present the design and implementation of an automated greenhouse in a home garden of Organic Solanum Lycopersicum, commonly known as organic tomatoes, controlled with fuzzy logic in a cold and humid climate, demonstrating that agroecological tomato greenhouses can be made in cold places without the use of chemicals, with the help of advanced controllers, in this case, a fuzzy controller. For the development, a diffuse controller was first designed, which has as inputs the temperature, relative humidity, soil humidity, and luminosity, and as outputs it controls an irrigation pump, halogen lights to provide heating and fans, all this information is processed by an Arduino development board that works as the central system of the greenhouse. After having the fuzzy controller, the greenhouse was built with recycled bags and sticks. The first tests that were carried out with the finished prototype were very satisfactory, so much so that the plants developed a large size and exceeded the measurements of the greenhouse initially manufactured. With this project, it was possible to develop a greenhouse with a diffuse control system, obtaining clear results, going from having sick plants with the tomato spotted wilt virus that were not more than 15 cm tall, to obtaining plants of Solanum Lycopersicum completely healthy over 1 meter tall. This greenhouse can be adapted to any type of requirement on a small or large scale to provide effective and efficient solutions.
