Welcome to PyMoDAQ’s documentation!

PyMoDAQ, Modular Data Acquisition with Python, is a set of python 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.

It 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 Application

It is divided in two main components as shown on figure Fig. 3


Fig. 1 PyMoDAQ’s Dashboard and its extensions: DAQ_Scan for automated acquisitions, DAQ_Logger for data logging and many other.

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
