Since the concept of automation is widespread nowadays, the objective of this work is to facilitate the cultivation of plants indoors. Through the concepts and technologies discussed in the classroom, a support system was developed to improve the quality of plants while preventing unnecessary water consumption. With the aid of technology, it is possible to improve the longevity of indoor plants without the need of manual watering. In order to make this project possible, an Arduino UNO board was used, which has the role of controlling the system through the processing of incoming signals from the external environment and outputting commands in answer to these signals. A humidity sensor was implemented in the planting area, in which an average soil moisture was established as the trigger to activate solenoid valves and perform irrigation until an ideal moisture level could be reached. As soon as the reference moisture is reached, the system implemented in Arduino stops irrigation through the closure of the valves, thereby blocking water flow. The system also provides real-time monitoring of soil moisture and solenoid valve status via an LCD screen. The practical study was undertaken using a fern sapling as a model. From the results, it can be realized that it is possible to create a financially viable automated irrigation system, enabling the use for indoor.
