Microgreens are young plants that have not gone through the full maturation period, resulting in smaller plants but rich in nutrients and flavors, making them highly recommended for restrictive diets focused on health and longevity. With the increasing demand for these products, solutions are emerging to supply the market; however, there are few options for domestic consumers to produce their own high-quality microgreens. Proper growth and maintenance of nutritional quality require an environment with good con-
trol of require an environment with good control of temperature, humidity, irrigation and lighting. This project aims to create an intelligent, automated, modular, and indoor greenhouse, allowing users to autonomously grow microgreens. Reference parameters are set based on recipes, featuring an efficient control system to manage the internal microclimate of the greenhouse, along with the integration of IoT technologies for data publishing and subscription for a monitoring system. As a test, basil was cultivated, taking 7 days to
germinate and 21 days to develop, reaching a size of 2 cm. During the testing period, the average temperature was maintained at 21.7 °C during the day, with a setpoint of 20 °C, and soil moisture was kept at 77%, with a predefined minimum of 75%. The temperature control system proved effective when heating the environment, generating an oscillating temperature range around the setpoint, with a maximum variation of 0.3 °C.
