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. ## Pricing - **Price:** $43.80 (inc GST) — $39.82 AUD, exc GST - **Quantity discounts:** 10+ $38.23 (exc GST) · 25+ $37.03 (exc GST) ## Availability & dispatch - In stock, ships same business day if ordered before 2PM (Australia/Sydney). - We can dispatch 3 today, and up to 100 more in 7–12 days. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE06393:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE06393:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description 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](https://github.com/pimoroni/max30105-python). It's also compatible with our fancy [Breakout Garden](https://core-electronics.com.au/breakout-garden-hat.html) 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](https://github.com/pimoroni/max30105-python) ### 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)* ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/m/a/max30105_4_of_4_large.jpg)
