Python API for Mentalab biosignal aquisition devices

Project description


Explorepy overview

Explorepy is an open-source Python API designed to collect and process biosignal data using Mentalab’s Explore device. Amongst other things, Explorepy provides the following features:

  • Real-time streaming of ExG, orientation and environmental data
  • Real-time visualization
  • Data recording in CSV and BDF+ formats
  • LSL integration
  • Impedance measurement
  • Explore device configuration

Quick installation

For Windows users, the best way to install Explorepy is to download the latest Explorepy version from the the release page or use pip. Please note that dependencies will install automatically from the release page.

For other operating systems, or to build the package manually on Windows, please refer to the information below.


  • Python 3.6 or newer versions
  • Visual Studio 2015 community edition (only Windows, in case of building the package)
  • Bluetooth header files (only Linux -> use this command: sudo apt-get install libbluetooth-dev)

Detailed installation instructions can be found on the installation page.

To install explorepy from PyPI run:

pip install explorepy

To install the latest development version (git must be installed before running this command):

pip install git+

Get started

CLI command

For a simple, quick start of Explorepy, run:

explorepy acquire -n Explore_XXXX

Enter explorepy -h for help.

Python code

When working in Python, the following connects to the Explore device and prints the data.

import explorepy
explorer = explorepy.Explore()
explorer.connect(device_name="Explore_XXXX")  # Put your device Bluetooth name

You can also visualize the data in real-time.

import explorepy
explorer = explorepy.Explore()
explorer.connect(device_name="Explore_XXXX")  # Put your device Bluetooth name
explorer.visualize(bp_freq=(.5, 30), notch_freq=50)
