Project description

MAX30105 - Heart Rate, Oximeter, Smoke Sensor

Build Status Coverage Status PyPi Package Python Versions

The MAX30105 is an precision optical sensor that can be used to measure heart rate, pulse oximetry (SPO2 / blood oxygen saturation), and smoke (and other particles).


Stable library from PyPi:

  • Just run sudo pip install max30105

Latest/development library from GitHub:

  • git clone
  • cd max30105-python
  • sudo ./


This code should not be used for medical diagnosis, as the basis for a real smoke or fire detector, or in life-critical situations. It's for fun/novelty use only, so bear that in mind while using it.



  • Bugfix: fix off-by-one error in sample average bitmask


  • Bugfix: fix timeout bug in get_temperature(), requires i2cdevice>=0.0.7


  • Bugfix: support 0 init value of MODE_CONFIG register


  • Port to i2cdevice>=0.0.6 set/get API
