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.

sl_sensor_light_set#

void sl_sensor_light_set (float lux, float uvi)

Parameters

Type	Direction	Argument Name	Description
float	[in]	lux	Ambient light illuminance (in lux).
float	[in]	uvi	UV index.

Setter for ambient light and UV index.

sl_sensor_lux_set#

void sl_sensor_lux_set (float lux)

Parameters

Type	Direction	Argument Name	Description
float	[in]	lux	Ambient light illuminance (in lux).

Setter for ambient light.
