The MAX30101 includes three LEDs and an optical detector in a single package, which can be utilized as a wearable, biosensor for pulse oximeter and heart-rate measurements. For accurate and reliable biometric readings, we recommend the SparkFun Pulse Oximeter and Heart Rate Sensor, which utilizes proprietary algorithms programmed on the MAX32664 Biometric Sensor Hub. Other possible applications include proximity sensing and particle detection by measuring the changes in light that is reflected back from the LEDs.
Required Materials
The Qwiic Photodetector Sensor does need a few additional items for you to get started. The RedBoard Qwiic will be used for the Arduino examples. A single board computer and the Qwiic pHAT are required for the Python examples (see note below). You may already have a few of these items, including the required Qwiic cable, so feel free to modify your cart based on your needs. Additionally, there are also alternative parts options that are available as well (click button below to toggle options).
