   :name: MAX32664C + MAX86141 Sensor Hub
   :relevant-api: sensor_interface

Get health data from a MAX32664C and a MAX86141 sensor (polling mode).

NOTE: This example requires sensor hub firmware 30.13.31!

Overview
********

This sample measures the heart rate and the blood oxygen saturation on a wrist.
It uses the MAX32664C sensor to control the MAX86141 sensor.

Requirements
************

This sample uses the MAX32664 sensor controlled using the I2C30 interface at
the nRF54L15-DK board.

Building and Running
********************

This project outputs sensor data to the console. It requires a MAX32664C
sensor to be connected to the desired board. An additional MAX86141 sensor
must be connected to the MAX32664C to provide the sensor data for the algorithms.
