BMP085/BMP18x digital pressure sensors
|
||||
|
||||
Required properties:
|
||||
- compatible: bosch,bmp085
|
||||
|
||||
Optional properties:
|
||||
- chip-id: configurable chip id for non-default chip revisions
|
||||
- temp-measurement-period: temperature measurement period (milliseconds)
|
||||
- default-oversampling: default oversampling value to be used at startup,
|
||||
value range is 0-3 with rising sensitivity.
|
||||
|
||||
Example:
|
||||
|
||||
pressure@77 {
|
||||
compatible = "bosch,bmp085";
|
||||
reg = <0x77>;
|
||||
chip-id = <10>;
|
||||
temp-measurement-period = <100>;
|
||||
default-oversampling = <2>;

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.

* 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.
