The purpose of this work is present the development of automatic instrument for measuring soil compaction through the penetration resistance. Commonly, this measurement is performed by load cells. In the proposed methodology and apparatus, the penetration resistance is directly measured by the current applied to the motor that performs penetration of the rod into the soil. The collected data are stored in data logger and further processed in order to enable analysis and the generation of maps of the surface with soil compaction values. The presented results indicate greater precision and control of the fundamental parameters of data acquisition.
