Abstract
This article presents a low-cost plant monitoring technology to assist in plants irrigation according to physiological demands. The project was conceived as a smart greenhouse capable of reporting on soil humidity, light and ambient temperature and presents principles of data-based agriculture. The methodology was based on engineering methods combined with design notions to adapt the technology to specific target audiences in a future stage of the project. Designed for small properties, the low-cost technological solution is an open technology that seeks to solve small farmers' pain regarding wasted resources in the field. The results are from isolated stages of the project, and point to correct data collection, processing using a microcontroller and sending the data for visualization on a dashboard. Future possibilities include a mathematical model based on the application of a differential equation to optimize the system, as well as building an application and carrying out integrative tests with tablets and other devices in a real production context.
