What:		/sys/bus/iio/devices/iio:deviceX/out_temp_raw
Date:		August 2021
KernelVersion:	5.15
Contact:	Andreas Klinger <[email protected]>
Description:
		Set the temperature. This value is sent to the sensor for
		temperature compensation.
		Default value: 25000 (25 °C)

What:		/sys/bus/iio/devices/iio:deviceX/out_humidityrelative_raw
Date:		August 2021
KernelVersion:	5.15
Contact:	Andreas Klinger <[email protected]>
Description:
		Set the relative humidity. This value is sent to the sensor for
		humidity compensation.
		Default value: 50000 (50 % relative humidity)

What:		/sys/bus/iio/devices/iio:deviceX/in_resistance_calibbias
Date:		August 2021
KernelVersion:	5.15
Contact:	Andreas Klinger <[email protected]>
Description:
		Set the bias value for the resistance which is used for
		calculation of in_concentration_input as follows:

		x = (in_resistance_raw - in_resistance_calibbias) * 0.65

		in_concentration_input = 500 / (1 + e^x)

		Default value: 30000
