Datasheet (MAX30101)Product Overview
The SparkFun Photodetector Breakout is an updated version of the SparkFun Particle Sensor Breakout, which includes the MAX30101, a highly sensitive optical sensor that succeeds the MAX30105 and MAX30102. The MAX30101 Breakout utilizes a photodiode to measure the amount of light reflected from the LEDs. This is useful for various applications, such as particle (i.e., smoke) detection, proximity measurements, and even photoplethysmography. To make it even easier to use this breakout, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken-out 0.1" spaced pins in case you prefer to use a breadboard.
For more 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.
