)

Retrieves the data signal representing humidity data Relative humidity is returned as a percentage.

Parameters

board

Board the humidity sensor resides on

Returns

Pointer to the data signal UINT32 is return signal data type

mbl_mw_humidity_bme280_set_oversampling()

METAWEAR_API void mbl_mw_humidity_bme280_set_oversampling	(	const MblMwMetaWearBoard *	board,
		MblMwHumidityBme280Oversampling	oversampling
	)

Sets the oversampling mode For the humidity measurement, oversampling is possible to reduce the noise.

The resolution of the humidity measurement is fixed at 16 bit ADC output. See MblMwHumidityBme280Oversampling for allowed oversampling values

Parameters

board	Board the humidity sensor resides on
oversampling	New oversampling mode
