MAX30102 Heart Rate Blood Oxygen Concentration Pulse Detection Sensor Module

Description

Description:
MAX30102 is an integrated module of pulse oximeter and heart rate monitor biosensor. It integrates a red LED, an infrared LED, a photoelectric detector, an optical device, and a low noise electronic circuit with ambient light suppression. MAX30102 uses a 1.8V power supply and an independent 5.0V power supply for internal LED. It is used in wearable devices for heart rate and blood oxygen collection and detection. It is worn on fingers, earlobes and wrists. The standard I2C compatible communication interface can transmit the collected values to Arduino, KL25Z and other microcontrollers for heart rate and blood oxygen calculation. In addition, the chip can also turn off the module by software, and the standby current is close to zero, so that the power supply can always maintain the power supply state.
