Abstract. Geoelectrical resistivity is an excellent method to investigate the structural composition of shallow subsurfaces. However, existing commercial equipment is typically expensive and often requires proprietary accessories and software to provide full system functionality. The objective of this study was to develop a multichannel, modular, automated, and programmable geo-resistivity meter capable of customization and programming by the user. To this end, a conceptual prototype was built based on free software and open hardware technologies as a low-cost alternative to commercial equipment, while maintaining the accuracy and quality of the data at the same level. The prototype was based on electrode multiplexing to make the switching process more efficient by reducing cabling complexity, while synchronous demodulation for signal detection was employed, providing strong rejection of spurious electrical noise, typical of urban areas where such equipment is frequently used. The results show the feasibility of this project and demonstrate an important academic contribution to open-source instrumental research.

Short summary
This project aims to demonstrate the viability of the development of a concept prototype that has, as a differential, free software and hardware used in its development and operation, and thus, has unique characteristics compared with commercially available equipment for signal detection was employed, providing strong rejection of spurious electrical noise, typical of urban areas. This project and important academic contribution to open-source instrumental research.
