摘要：This paper presents the values obtained with electrical resistance sensors, and collected through an Arduino microcontroller. These data were compared with the results obtained in the laboratory and had a correlation coefficient of 92%. The data obtained from the sensors, collected and stored by a microcontroller can assist in precision agriculture, due to greater accessibility to them. Additionally, the proposed system presents itself as a new way to automate the data collection of soil and to work with these data.
