The MAX30105 breakout is a sophisticated heart rate, oximeter, and smoke/particle sensor. Use it as a fun way to see your heartbeat, or to make LEDs or lights pulse in time with your heart. It's Raspberry Pi and Arduino-compatible. This sensor has three LED-green, red, and infra-red-and photodetectors that can be used together to detect the amount of light reflected back to the sensor. A technique called photoplethysmography (PPG) can be used to detect the change in colour of your skin with each beat of your heart when the sensor is pressed against your fingertip.

You can use the MAX30105 to detect particles in the air, like smoke, by measuring the amount of light bounced back to the sensor by the particles.

This sensor (and the code in our Python library) 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.
