What: /sys/bus/iio/devices/iio:deviceX/out_temp_raw
Date: August 2021
KernelVersion: 5.15
Contact: Andreas Klinger <ak@it-klinger.de>
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 <ak@it-klinger.de>
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 <ak@it-klinger.de>
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
