Function Documentation#

sl_sensor_light_init#

sl_status_t sl_sensor_light_init (void )
Parameters
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
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.
