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 without having to write a user/interface for each new experiment, this is under the DAQ Scan environment.
  • Second, to provide various tools (modules) to easily build a Custom Application

It is divided in three main modules:

  • DAQ Scan : This is the module that will initialize all preset actuators and detectors. Then will automate the data acquisition.
  • DAQ Move : used to control/drive an actuator (stand alone and/or automated). Any number of these modules can be instantiated.
  • DAQ Viewer : used to control/drive a detector (stand alone and/or automated). Any number of these modules can be instantiated.

and many others to simplify any application development.
