OhmPi project
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.

Introduction
The OhmPi project was initiated to develop an open-source, open-hardware resistivity meter, particularly designed for the research community, education, and humanitarian or not-for-profit organisations. In the last decade, geoelectrical monitoring has become a popular tool to study and monitor physical processes in hydrology. As novel applications emerge, the need for more accessible and flexible acquisition systems grows in the research community. The flexibility and adaptability of OhmPi makes it particularly suited to develop novel acquisition strategies or design innovative small-scale monitoring experiments.
