Welcome to PyMoDAQ’s documentation!

PyMoDAQ is an open-source software, officially supported by the CNRS, to perform modular data acquisition with Python. It proposes a set of modules used to interface any kind of experiments. It simplifies the interaction with detector and actuator hardware to go straight to the data acquisition of interest.

PyMoDAQ has two purposes:

  • First, to provide a complete interface to perform automated measurements or logging data without having to write a user/interface for each new experiment.

  • Second, to provide various tools (User interfaces, classes dedicated to specific tasks…) to easily build a Custom App

It is divided in two main components as shown on figure Fig. 2

The Control modules are interfacing real instruments using user written plugins. The complete list of available plugins is maintained on this GitHub repository and installabled using the Plugin Manager
