Description: Start a pressure measurement and read the result. Values
|
||
|
|
represent the ambient air pressure in pascal (0.01 millibar).
|
||
|
|
|
||
|
|
Reading: returns the current air pressure.

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

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