You can use it as a fun way to see your heart rate or have LEDs or lights pulsate to the rhythm of your heart. It is compatible Raspberry Pi and Arduino.
This sensor has three LEDs - green, red and infrared - 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 color of your skin with each heartbeat when the sensor is pressed against your fingertip.
You can use the MAX30105 to detect particles in the air, such as smoke, by measuring the amount of light reflected back to the sensor by the particles.
It is also compatible with the Breakout Garden. Simply slip it into one of the 6 slots provided before you start developing your project, creating and coding.
This sensor (and our Python library code) is not to be used for medical diagnosis, as a basis for a real smoke or fire detector, or in critical situations. It's only for fun / novelty, so keep that in mind when using it.
Kit includes:
- 1 MAX30105
- 1x5 male header
- 1x5 female header right angle
Check out an example of how you can create a small heart rate display with the MAX30105 breakout, the 1.12" OLED breakout and a Garden HAT or pHAT breakout.
SparkFun has put together a really comprehensive Arduino library for the MAX30105 sensor that also includes examples of blood oxygen saturation (SPO2), temperature and presence detection measurements.
Our software does not support Raspbian Wheezy.
When measuring heart rate with the MAX30105 sensor, you will get much more reliable readings if you attach the sensor to your fingertip (the fleshy side) with a piece of wire or elastic band looped through the mounting holes on the break.
