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.
1. Circuit Board Size: 18*15mm
2. Circuit Board Thickness: 2.5mm
3. Peak Wavelength of LED: 660 nm/880 nm
4. LED Supply Voltage: 3.3~5v
5. Detection Signal Type: Optical Reflection Signal (PPG)
6. Output Signal Interface: I2C Interface
7. Communication Interface Voltage: 1.8~5V
8. Reserved assembly hole size：0.5x8.5mm
Interface Description:
1. VIN: LED power input terminal, also I2C bus pull-up level, it is recommended to connect 3.3V or 5V
2. SCL: I2C bus clock
3. SDA: I2C bus data
4. INT: MAX02 chip interrupt pin
5. RD: MAX30102 chip's RD LED grounding terminal, generally does not connect
6. IRD: MAX30102 chip's IR LED grounding terminal, generally does not connect
7. GND: grounding wire.
Note: Oxygen saturation measurement requires professional instrument calibration and is related to the module temperature. Therefore, the oxygen saturation calculated by using the algorithm program can not guarantee certain accuracy.
Package included:
1 x MAX30102 Heart Rate Blood Oxygen Sensor Module Puls Detection Tester
