While the latter does all the sensing, the former is an incredibly small and fast Cortex M4 processor that handles all of the algorithmic calculations, digital filtering, pressure/position compensation, advanced R-wave detection, and automatic gain control. We've provided a Qwiic connector to easily connect to the I2C data lines but you will also need to connect to two additional lines. This board is very small, measuring at 1in x 0.5in (25.4mm x 12.7mm), which means it will fit nicely on your finger without all the bulk.The MAX30101 does all the sensing by utilizing its internal LEDs to bounce light off the arteries and arterioles in your finger's subcutaneous layer and sensing how much light is absorbed with its photodetectors. This is known as photoplethysmography. This data is passed onto and analyzed by the MAX32664 which applies its algorithms to determine heart rate and blood oxygen saturation (SpO2). SpO2 results are reported as the percentage of hemoglobin that is saturated with oxygen. It also provides useful information such as the sensor's confidence in its reporting as well as a handy finger detection data point. To get the most out of the sensor we've written an Arduino Library to make it easy to adjust all the possible configurations.The SparkFun Qwiic connect system is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.GET STARTED WITH THE PULSE OXIMETER AND HEART RATE MONITOR HOOKUP GUIDE **Product Type:** physical ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD2hcBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--6205bece1c7111ecfbcb5f81e493da5af1b0ddf4/15219-SparkFun_Pulse_Oximeter_and_Heart_Rate_Sensor_-_MAX30101__Qwiic_-01.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD2xcBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--d691c26e8bbeb97e111dfbcf77a0cfbecec2aef2/15219-SparkFun_Pulse_Oximeter_and_Heart_Rate_Sensor_-_MAX30101__Qwiic_-02.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD3BcBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--5a63f4c04be3cc8c7da7eb3e8b5fca23e277c0c5/15219-SparkFun_Pulse_Oximeter_and_Heart_Rate_Sensor_-_MAX30101__Qwiic_-03.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD3RcBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--f12580caafec7114da0b3d82ca0fc9dd23b42ef0/15219-SparkFun_Pulse_Oximeter_and_Heart_Rate_Sensor_-_MAX30101__Qwiic_-04.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD3hcBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--9b83085dcb7942c0400dd90c8e87a058adc9b37f/15219-SparkFun_Pulse_Oximeter_and_Heart_Rate_Sensor_-_MAX30101__Qwiic_-05.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
