- This driver supports the bmp085 digital barometric pressure
- and temperature sensor from Bosch Sensortec. The datasheet
- is available from their website:
- http://www.bosch-sensortec.com/content/language1/downloads/BST-BMP085-DS000-05.pdf
-
- A pressure measurement is issued by reading from pressure0_input.
- The return value ranges from 30000 to 110000 pascal with a resulution
- of 1 pascal (0.01 millibar) which enables measurements from 9000m above
- to 500m below sea level.
-
- The temperature can be read from temp0_input. Values range from
- -400 to 850 representing the ambient temperature in degree celsius
- multiplied by 10.The resolution is 0.1 celsius.
-
- Because ambient pressure is temperature dependent, a temperature
- measurement will be executed automatically even if the user is reading
- from pressure0_input. This happens if the last temperature measurement
- has been executed more then one second ago.
-
- To decrease RMS noise from pressure measurements, the bmp085 can
- autonomously calculate the average of up to eight samples. This is
- set up by writing to the oversampling sysfs file. Accepted values
- are 0, 1, 2 and 3. 2^x when x is the value written to this file
- specifies the number of samples used to calculate the ambient pressure.
- RMS noise is specified with six pascal (without averaging) and decreases
- down to 3 pascal when using an oversampling setting of 3.
