Python API for Mentalab biosignal aquisition devices

Project description


Explorepy overview

Explorepy is Mentalab’s open-source Python-based biosignal acquisition API for working with Mentalab Explore device. Amongst many things, it 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


  • Python 3.5 or newer version
  • Visual Studio 2015 community edition (only Windows)
  • Bluetooth header files (only Linux -> use this command: sudo apt-get install libbluetooth-dev)

Please check out the installation page for more detailed instructions.

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)
