| :name: Heart Rate Sensor |
| :relevant-api: sensor_interface |
| |
| Get heart rate data from a sensor (polling mode). |
| |
| Overview |
| ******** |
| |
| A sensor application that demonstrates how to poll data from a heart rate |
| sensor. |
| |
| Requirements |
| ************ |
| |
| * A supported heart rate sensor (e.g., MAX30101 or BH1790), available as ``heart-rate-sensor`` Devicetree alias. |
| |
| Building and Running |
| ******************** |
| |
| This project configures a sensor on the board to enable the green LED and |
| measure the reflected light with a photodiode. The raw data prints to the |
| console. Further processing (not included in this sample) is required to |
| extract a heart rate signal from the light measurement. |
