| :name: Generic Light Sensor Polling |
| :relevant-api: sensor_interface |
| |
| Get illuminance data from a light sensor. |
| |
| Overview |
| ******** |
| |
| This sample application gets the output of the light sensor and prints it to the console, in |
| units of lux, once every second. |
| |
| Requirements |
| ************ |
| |
| To use this sample, the following hardware is required: |
| |
| * A board with ADC support |
| * A supported light sensor (e.g., `Grove Light Sensor`_), available as ``light-sensor`` Devicetree alias. |
| |
| Wiring |
| ****** |
| |
| The wiring depends on the specific light sensor and board being used. Provide a devicetree |
| overlay that specifies the sensor configuration for your setup. |
| |
| Building and Running |
| ******************** |
| |
| Build and flash the sample as follows, changing ``nrf52dk_nrf52832`` to your board: |
| |
