Desenvolvimento de um instrumento digital microcontrolado para obtenção do coeficiente de permeabilidade de solos

Abstract

This work presents the design of a digital microcontroller instrument to be coupled to a device for permeability testing, in order to perform the automatic acquisition of data for determining the soil permeability coefficient. The project, initiated by observing the difficulties encountered during the manual procedure to obtain the permeability coefficient, aims to minimize operator errors during the experiment. This document includes all stages of the development of this project, from the study of the problem and the technologies to be used, integration of hardware and software modules until the implementation in the lab. At the end, presented the prototype of the developed digital instrument and the satisfactory results obtained, which were within the order of magnitude expected by Mechanics Soil literature. The tests were carried out in the Laboratory of Soil Mechanics of the UTFPR.
