The MAX30102 is an integrated pulse oximeter and heart rate monitor biosensor module. It integrates a red LED and an infrared LED, photodetector, optical components, and low-noise electronic circuitry with ambient light suppression. The MAX30102 features a 1.8V power supply and a separate 5.OV power supply for internal LEDs. It is used in wearable devices for heart rate and blood oxygen acquisition, and is worn on fingers, earlobes, and wrists. The standard 12C-compatible communication interface can transmit 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, the standby current is close to zero, and the power supply is always maintained. Because of its excellent performance, the chip is widely used in the Samsung Galaxy S series mobile phones. Compared with the previous generation MAX30100, the chip integrates a glass cover to effectively eliminate external and internal light interference, and has the best reliable performance.

Features:

• LED peak wavelength 660nm/880nm
• LED supply voltage: 3.3–5v
• Output signal connection: 12C connection
• Communication interface voltage: 1.8, 3.3V, 5V (optional)
• Board reserved assembly hole size: 0.5×8.5 mm

Pin Description:

• VIN: main power supply input, 1.8V-5V
• 3-bit pad: Select the pull-up level of the bus, depending on the pin master voltage, select 1.8v or 3.3v (this terminal contains 3.3V and above)
• SCL: Clock connected to 12C bus
• SDA: Connect the data of the 12C bus
• INT: interrupt pin of the MAx30102 chip
• RD: RED LED ground terminal of MA×30102 chip, generally not connected
• IRD: IR LED ground terminal of MA×30102 chip, generally not connected
• GND: Ground wire

• Note:- For this sensor you have to pull up SCL & SDA Pin( You have to connect 10Kohm resistor between SCL & 5V And Same as SDA to 5V)

Package Includes:
