Introduction
Warning
OhmPi is a participative project open to all, it requires skills in electronics and to respect the safety rules. OhmPi must be assembled in a professional context and by people competent in electronics. The OhmPi team cannot be held responsible for any material or human damage which would be associated with the use or the assembly of OhmPi. The OhmPi team cannot be held responsible if the equipment does not work after assembly.

Please see the CERN-OHL-P v2 for applicable conditions.
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 64 electrodes.OhmPi’s philosophy is to provide a fully open source and open hardware toolto the near surface scientific community.
Note
Anyone who wants to get involved is welcome to join the OhmPi project!
