Heart Rate Sensor Module MAX30102 Blood Oxygen Sensor Pulse Detection

PULSE OXIMETER & HEART RATE MONITOR MODULE

MAX30102 is an integrated module of heart rate monitor biosensor. It integrates a red LED with an infrared LED, a photoelectric detector, an optical device, and a low noise electronic circuit with ambient light suppression.
LED peak wavelength: 660nm/880nm; LED power supply voltage: 3.3~5V; Detection Signal Type: Optical Reflection Signal (PPG); Output Signal Interface: I2C Interface; Communication Interface Voltage: 1.8 ~3.3V~ 5V.
Application: MAX30102 is used in wearable equipment for heart rate and blood oxygen acquisition and detection. It is worn on fingers, earlobes and wrists.The standard I2C compatible communication interface can transmit the collected data to KL25Z and other microcontrollers for heart rate and blood oxygen calculation.
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 be maintained.
