  5. Description:
  6. Set the temperature. This value is sent to the sensor for
  7. temperature compensation.
  8. Default value: 25000 (25 °C)

  13. Description:
  14. Set the relative humidity. This value is sent to the sensor for
  15. humidity compensation.
  16. Default value: 50000 (50 % relative humidity)
  17. What: /sys/bus/iio/devices/iio:deviceX/in_resistance_calibbias
  18. Date: August 2021

  20. Contact: Andreas Klinger <[email protected]>
  21. Description:
  22. Set the bias value for the resistance which is used for
  23. calculation of in_concentration_input as follows:
  24. x = (in_resistance_raw - in_resistance_calibbias) * 0.65
  25. in_concentration_input = 500 / (1 + e^x)
  26. Default value: 30000
