Maxim Integrated MAX30102 Pulse Oximeter & Heart-Rate Sensor
Maxim Integrated MAX30102 Sensor is an integrated pulse oximetry and heart-rate monitor module. The MAX30102 includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. This highly sensitive device 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. This sensor can be shut down through software with zero standby current, allowing the power rails to remain powered at all times.
