Pimoroni MAX30105 Breakout - Heart Rate, Oximeter, Smoke Sensor

SKU: CE06393 Brand: Pimoroni

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. <3 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. Pimoroni has got a rough example of how to do this in Pimoroni's Python library.

It's also compatible with our fancy Breakout Garden HAT, where using breakouts is as easy just popping it into one of the six slots and starting to grow your project, create, and code.

If you're using the MAX30105 with Breakout Garden for measuring heart rate, then we'd recommend using one of our Breakout Garden Extender Kits along with some female-to-female jumper jerky (available as Essential extras on this page). This will make it much easier to get reliable heartbeat readings. See Notes below for more information.

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.

Features

MAX30105 - heart rate, oximeter, smoke sensor (datasheet)
Green, red, and infra-red LEDs
Photodetectors
Ambient light rejection
Temperature sensor
I2C interface (address 0x57)
3.3V or 5V compatible
Reverse polarity protection
Compatible with all models of Raspberry Pi, and Arduino
Python library

Kit includes

MAX30105 breakout
1x5 male header
1x5 female right-angle header

Pimoroni has designed this breakout board so that you can solder on the piece of right-angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 7, 9).

Heart rate example

Pimoroni has added a new example to our Breakout Garden GitHub repo, showing how you can create a little heart rate display with the MAX30105 breakout, 1.12" OLED breakout, and a Breakout Garden HAT or pHAT.

Here it is in action:

Software

Pimoroni Python library makes it straightforward to use your MAX30105 sensor. Pimoroni has included some examples of how to display and graph and display heart rate, and a rough example of how to detect relative levels of particles like smoke.

SparkFun have put together a really comprehensive Arduino library for the MAX30105 sensor that also includes examples of how to measure blood oxygen saturation (SPO2), temperature, and presence detection.

Pimoroni's software does not support Raspbian Wheezy.

Notes

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.
When measuring heart rate with the MAX30105 sensor, you'll get much more reliable readings if you attach the sensor to your fingertip (the fleshy side) with a piece of wire or rubber band looped through the mounting holes on the breakout
Dimensions: 19x19x3.2mm (LxWxH)
