The MAX30102 is integrated pulse oximetry and heart-rate monitor biosensor module. It includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. It provides a complete system solution to ease the design-in process for mobile and wearable devices. This module can operates on a single 1.8V power supply and a separate 5.0V power supply for the internal LEDs. Communication is through a standard I2C-compatible interface. It also has a proximity function to save energy and reduce the emission of visible light when the user's finger is not on the sensor. The module can be shut down via software. In standby, the current consumption is almost zero (0.7 µA). I2C communication interface, 2.5 to 5.5 VDC power supply, operating temperature: -40 ° C to + 85 ° C, dimensions (mm): 12.7x12.7x4.
