lm_sensors-3.4.0
Kernel
Configuration
Getting your kernel config right is an iterative process that may
require that you recompile your kernel a couple of times. The
simplest way to go about it is to start by enabling modules and
then compile everything that may be needed by Lm Sensors as a
module:
[*] Enable loadable module support ---> [CONFIG_MODULES]
Bus options (PCI etc.) --->
[*] PCI support [CONFIG_PCI]
Device Drivers --->
I2C support --->
<*/M> I2C device interface [CONFIG_I2C_CHARDEV]
I2C Hardware Bus support --->
<M> (configure all of them as modules)
<*/M> Hardware Monitoring support ---> [CONFIG_HWMON]
<M> (configure all of them as modules)
Recompile your kernel and reboot into the new kernel. Don't forget
to make
modules_install We will come back to the kernel in
the Configuring section below.
Installation of lm_sensors
Install lm_sensors by running the
following commands:
make PREFIX=/usr \
BUILD_STATIC_LIB=0 \
MANDIR=/usr/share/man
This package does not come with a test suite.
Now, as the root user:
make PREFIX=/usr \
BUILD_STATIC_LIB=0 \
MANDIR=/usr/share/man install &&
install -v -m755 -d /usr/share/doc/lm_sensors-3.4.0 &&
cp -rv README INSTALL doc/* \
/usr/share/doc/lm_sensors-3.4.0
Command Explanations
BUILD_STATIC_LIB=0: This
parameter disables compiling and installing the static version of
libsensors.
PROG_EXTRA=sensord: This
parameter enables compiling sensord, a daemon that can
monitor your system at regular intervals. Compiling sensord requires RRDtool. Compiling
RRDtool 1.4.6 requires a sed: sed -i
'/ sv_undef/d' bindings/perl-shared/RRDs.xs.
Configuring Lm Sensors
Config
File
/etc/sensors3.conf
Configuration Information
To find out what hardware sensors your system has, issue the
following command as the root
user:
sensors-detect
The appropriate modules should have been loaded and a summary is
displayed at the end. Now you know what is needed and you can
recompile your kernel to enable just the options you need (i.e.,
don't enable the modules you cannot use).

Short Descriptions
|
fancontrol
|
is a shell script for use with lm_sensors. It reads its
configuration from a file, then calculates fan speeds
from temperatures and sets the corresponding PWM outputs
to the computed values.
|
|
isadump
|
is a small helper program to examine registers visible
through the ISA bus. It is intended to probe any chip
that lives on the ISA bus working with an address
register and a data register (I2C-like access) or a flat
range (of up to 256 bytes).
|
|
isaset
|
is a small helper program to set registers visible
through the ISA bus.
|
|
pwmconfig
|
tests the pulse width modulation (PWM) outputs of sensors
and configures fancontrol.
|
|
sensors
|
prints the current readings of all sensor chips.
|
|
sensors-conf-convert
|
is a Perl script to
convert lm-sensors
version 2 configuration files to work with version 3.
|
|
sensors-detect
|
is a Perl script that
will walk you through the process of scanning your system
for various hardware monitoring chips (sensors) supported
by libsensors, or more
generally by the lm_sensors tool suite.
|
|
sensord
|
(optional) is a daemon that can be used to periodically
log sensor readings.
|
|
libsensors.so
|
contains the lm_sensors
API functions.
