Introduction to OhmPi

This documentation presents the development of a low-cost, open hardware resistivity meter to provide the scientific community with a robust and flexible tool for small-scale experiments. Called OhmPi, this basic resistivity meterfeatures current injection and measurement functions associated with a multiplexer that allows performing automatic measurements with up to 32 electrodes.OhmPi’s philosophy is to provide a fully open source and open hardware tool / to the near surface scientific community.
