| :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. |
