<p>A virtual environment is a way to have multiple, parallel instances of the Python interpreter, each with different package sets and different configurations.
Each virtual environment contains a discrete copy of the Python interpreter, including copies of its support utilities. It also protects your system in case of problems with the packages.</p>

<p>The multiplexing of the channels is a mechanical multiplexing based on OMRON’s manufacturing relays (G5LE-1-VD 12 VDC). Each relay is combined with
a ZVN4206A power MOFSET. The raspberry has only 30 GPIOs, which is not enough to activate all the 64 electrodes, which represent 512 GPIOs.
We used gpio expender I2C (MCP23017). We have associated these components with an I2C muliplexer of type type TCA9548A from adafruit.

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.

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 meter\
features 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 /
OhmPi's philosophy is to provide a fully open source and open hardware tool\
to the near surface scientific community.
