The MAX30101EFD+ is a low-power, integrated pulse oximetry and heart-rate monitor module. It combines two LEDs, a photodetector, and an analog front-end into a single, compact package. The module is capable of measuring both SpO2 and heart rate from a fingertip.

The MAX30101EFD+ operates from a single 1.8V supply and consumes only 1.2mA of current during normal operation. The module is also available in a shutdown mode, which reduces the current consumption to only 0.1µA.

The MAX30101EFD+ is controlled by a simple I2C interface. The module can be configured to take measurements at different rates, and the data can be read out in either raw or processed form.

The MAX30101EFD+ is a versatile and easy-to-use module that is ideal for a variety of applications, including:

  • Fitness and wellness devices
  • Medical devices
  • Wearables
