MAX30101 Breakout - Heart Rate, Oximeter, Smoke Sensor

The MAX30101 breakout is a sophisticated heart rate, oximeter, and smoke/particle sensor, compatible with Raspberry Pi and Arduino. It features three LEDs (green, red, and infra-red) and photodetectors to detect the amount of light reflected back. Using photoplethysmography (PPG), it can detect skin color changes with each heartbeat when pressed against a fingertip.

This sensor can also detect particles in the air, like smoke, by measuring the light bounced back by particles. It's compatible with the Breakout Garden HAT for easy integration.
