   4 Description:    Start a pressure measurement and read the result. Values
   5                 represent the ambient air pressure in pascal (0.01 millibar).

   7                 Reading: returns the current air pressure.

  13 Description:    Measure the ambient temperature. The returned value represents
  14                 the ambient temperature in units of 0.1 degree celsius.
  15
  16                 Reading: returns the current temperature.

  22 Description:    Tell the bmp085 to use more samples to calculate a pressure
  23                 value. When writing to this file the chip will use 2^x samples
  24                 to calculate the next pressure value with x being the value
  25                 written. Using this feature will decrease RMS noise and
  26                 increase the measurement time.
  27
  28                 Reading: returns the current oversampling setting.
  29
  30                 Writing: sets a new oversampling setting.
