MAX30101
High-Sensitivity Pulse Oximeter and
Heart-Rate Sensor for Wearable Health
General Description
The MAX30101 is an integrated pulse oximetry and
heart-rate monitor module. It includes internal LEDs,
photodetectors, optical elements, and low-noise electronics
with ambient light rejection. The MAX30101 provides a
complete system solution to ease the design-in process
for mobile and wearable devices.
The MAX30101 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. The module can be shut down through software
with zero standby current, allowing the power rails to
remain powered at all times.
