Description
MAX30102 integrates a red LED, a infrared LED, aphotodetector, an optical equipment and a low noise electronic circuit with environmental light suppression. Adopts standard I2C compatible communication interface can transmit the collected data to microcontrollers for heart rate and blood oxygen calculation. And the standby current can always maintain close to zero by turn off the module by software.
