Function Documentation#

sl_sensor_rht_init#

sl_status_t sl_sensor_rht_init (void )
Parameters
TypeDirectionArgument NameDescription
voidN/A

Initialize Relative Humidity and Temperature sensor.

Note

  • With certain boards (e.g. 4166A, 4184A, 4184B), 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_rht_deinit#

void sl_sensor_rht_deinit (void )
Parameters
TypeDirectionArgument NameDescription
voidN/A

Deinitialize Relative Humidity and Temperature sensor.

Warnings

  • With certain boards (e.g. 4166A, 4184A, 4184B), using this deinitialization function disables other sensors, because they're on the same enable pin. Please use with caution.

sl_sensor_rht_get#

sl_status_t sl_sensor_rht_get (uint32_t * rh, int32_t * t)
Parameters
TypeDirectionArgument NameDescription
uint32_t *[out]rh

Relative humidity (in 0.001 percent).

int32_t *[out]t

Temperature (in 0.001 Celsius).

Getter for Relative Humidity and Temperature sensor measurement data. Returns

  • Status of the operation.
