MAX30105 Particle and Pulse Oximeter Sensor

MAX30105 is an integrated particle detection module. It has a built-in LED, photodetector, optical components, and a high SNR circuit with ambient light suppression, as well as reliable motion artifact suppression. This simplifies the smoke detection process for fire alarm lamps. Thanks to its extremely small size, it can also be used for smoke detection sensors in mobile and wearable devices.
