SPARKFUN PARTICLE AND PULSE OXSENSOR BREAKOUT - MAX30105
The SparkFun MAX30105 Particle Sensor is a flexible and powerful sensor enabling sensing of distance, heart rate,
particle detection, even the blinking of an eye. This tutorial will get you up and running to get the raw data from
the sensor. The MAX30105 has three on-board LEDs (seen on the left). Maxim recommends these LEDs be powered
from 5V, but we've found the LEDs work fine at 3.3V. The red and IR LEDs are guaranteed to work at 3.3V, but the
green LED may need 3.5V. It's best to try out your board at 3.3V and see if the green LED illuminates. The IC itself
runs at 1.8V, so we’ve included the interface logic to allow you to hook the MAX30105 Breakout Board to any board
that has 5V, 3.3V, even 1.8V level I/O. The GND/5V/SDA/SCL pin-out is the standard I2C connection on most of our
products. This allows you to easily connect I2C boards to many of our platforms.
