Use it as a fun way to see your heartbeat, or to make LEDs or lights pulse in time with your heart. \u0026lt;3 It's Raspberry Pi and Arduino-compatible.\u003c\/p\u003e\n\u003cp\u003eThis sensor has three LED—green, red, and infra-red—and photodetectors that can be used together to detect the amount of light reflected back to the sensor. A technique called photoplethysmography (PPG) can be used to detect the change in colour of your skin with each beat of your heart when the sensor is pressed against your fingertip.\u003c\/p\u003e\n\u003cp\u003eYou can use the MAX30101 to detect particles in the air, like smoke, by measuring the amount of light bounced back to the sensor by the particles.
