Function Documentation#
sl_sensor_light_init#
sl_status_t sl_sensor_light_init (void )
Parameters
| Type | Direction | Argument Name | Description |
|---|---|---|---|
| void | N/A |
Initialize ambient light and UV index sensor.
Note
With certain boards (e.g. 4166A, 4184A), using this initialization function enables other sensors, because they're on the same enable pin. Please take that into account when using this function.
Returns
Status of the operation.
sl_sensor_light_deinit#
void sl_sensor_light_deinit (void )
Parameters
| Type | Direction | Argument Name | Description |
|---|---|---|---|
| void | N/A |
Deinitialize ambient light and UV index sensor.
Warnings
With certain boards (e.g. 4166A, 4184A), using this deinitialization function disables other sensors, because they're on the same enable pin. Please use with caution.
sl_sensor_light_get#
sl_status_t sl_sensor_light_get (float * lux, float * uvi)
Parameters
| Type | Direction | Argument Name | Description |
|---|---|---|---|
| float * | [out] | lux | Ambient light illuminance (in lux). |
| float * | [out] | uvi | UV index. |
Getter for ambient light and UV index sensor measurement data. Returns
Status of the operation.
