<p>The philosophy of Ohmpi V1.01 is to offer a multi electrode resistivity meter, from a set of commercially available
electronic cards it is a resistivity meter limited to 32 electrodes only. It is limited to low-current injection,
but suitable for small laboratory experiments and small field time monitoring</p>

input signal value could lie between - to + 6.114 V. The ADS1115 is mounted on a board adapted from an in-house design.

<p>The philosophy of Ohmpi V2.00 is to offer a new DIY multielectrode resistivity meter. It is a resistivity meter with 64 electrodes , which can be upgraded to 128 electrodes.
It is limited to low-current injection,but suitable for small laboratory experiments and small field time-lapse monitoring.
Ohmpi, is developed by a team that seeks to share all its experience and wishes to improve and offer a more and more robust tool to the community.Ohmpi V2.00 is a completely different version from the previous one.
We will stop the development on the previous version, to dedicate our efforts on this new version.</p>

features current injection and measurement functions associated with a multiplexer \
that allows performing automatic measurements with up to 32 electrodes.\
