24 and temperature family. Temperature is measure 24 and temperature family. Temperature is measured in degrees celsius, relative
25 humidity is expressed as a percentage. In the 25 humidity is expressed as a percentage. In the sysfs interface, all values are
26 scaled by 1000, i.e. the value for 31.5 degree 26 scaled by 1000, i.e. the value for 31.5 degrees celsius is 31500.
