Introduction:
The MAX30102 is an integrated pulse oximeter and heart rate monitor biotransmission the module of the senso. It integrates a red LED and an infrared LED, photo electric detectors, optical devices and low-noise electronic circuits with ambient light suppression. The MAX30102 features a 1.8V supply and a separate 5.0V for internal LED power supply for wearable devices for heart rate and blood oxygen collection detection. Wear on your fingers, earlobe and wrist. Standard I2C compatible communication interface can transfer the collected values to the Arduino, KL25Z and other microcontrollers for heart rate and blood oxygen calculation. In addition, the chip can also shut down the module through software, standb by current nearly zero, the power supply is always maintained. Because of its excellent performance, the chip is used in a large number of Samsung Galaxy S series phones.

Main parameters: 
LED peak wavelength: 660nm/880nm
LED power supply voltage: 3.3V~5V
Detection signal type: light reflection signal (PPG)
Output signal interface: I2C interface
Communication interface voltage: 1.8V~3.3V~5V (optional)
Board reserved assembly hole size: 0.5*8.5mm

Principle description:
-Photodissolution method:
 The measurement of pulse and blood oxygen saturation is performed by using human tissue to cause different light transmittance when the blood vessel beats.
-Light source: 
 A specific wavelength of  light-emitting diode selective for oxyhemoglobin (HbO2) and hemoglobin (Hb) in arterial blood.
-Light transmittance is converted into an electrical signal:
 The change in the volume of the arterial pulsation causes the light transmittance of the light to change. At this time the light reflected by the human tissue is received by the photoelectric transducer, converted into an electrical signal and amplified and output.

Pin description:
VIN: main power supply input, 1.8V~5V
3-bit pad: selects the pull-up level of the bus, depending on the pin master voltage, optional 1.8V or 3.3V end (this end contains 3.3V and above)
SCL: the clock connected to the I2C bus
SDA: data connected to the I2C bus
INT: interrupt pin of the MAX30102 chip
RD: RED LED ground terminal of MAX30102 chip, generally not connected
IRD: the IR LED ground of the MAX30102 chip is generally not connected
GND: ground wire
