  MAX30102 blood oxygen concentration sensor.
  An integrated pulse oximeter and heart rate monitor biosensor module.
  It uses an 18V power supply and an independent 50V power supply for internal LEDs, which are used in wearable devices for heart rate and blood oxygen collection and detection.

  1.It uses a standard 12C compatible communication interface,and can transmit the collected values to the single-chip computer for heart rate and blood oxygen calculation.
  2.It can effectively eliminate the external and internal light resistance and has reliable performance.
  3.It can shut down the module through software,the standby current is close to zero, and the power supply can always maintain the power supply state.
  4.It integrates a red LED and an infrared LED,photodetectors,optical devices, and low-noise electronic circuits with ambient light suppression.
