获取 lm_sensors 2.6.2 或更新版本：http://www.lm-sensors.nu/archive/lm_sensors-2.6.2.tar.gz 你也需要内核源代码来编译它。
tar -xzvf i2c-2.6.2.tar.gz
cd i2c-2.6.2
make && make install
然后我在进行安装时遇到了问题，所以如果它不起作用，请执行以下操作
cp kernel/i2c-core.o /lib/modules/`uname -r`/misc/i2c-core.o
cp kernel/i2c-proc.o /lib/modules/`uname -r`/misc/i2c-proc.o
现在让我们复制特定的驱动程序
cp kernel/chips/it87.o /lib/modules/`uname -r`/misc/it87.o
好的，现在
cp prog/sensors/sensors /usr/bin/sensors
--------------------------------------------------------------------
编辑 /etc/modules.conf 并添加以下行
alias char-major-89 i2c-dev
options it87 temp_type=0x31
现在
modprobe i2c-proc
modprobe it87
modprobe i2c-isa
sensors
应该输出一些数据
当它工作时，你可以把它写入到一个文件，该文件将在启动时自动加载。在 SuSE 下，该文件是：/etc/init.d/boot.local (以前是 /sbin/init.d/)，你应该 просто 添加：sensors -s 在 Mandrake 下，安装应该已经创建了该文件：/etc/init.d/sensors，你可以自由编辑它，sensord 只是一个守护进程，用于监视温度和风扇速度，我假设没有人会为她/他自己的机器需要这样的东西。
Paolo 报告说，为了在启动时启动 sensord，他将其放在 /etc/sysconfig/sensors 中
MODULE_0=i2c-proc
MODULE_1=it87
MODULE_2=i2c-isa
现在以 root 用户身份，你应该编辑你的 /etc/sensors.conf，搜索这一行：chip "it87-*"，在下面你应该能够修改一切以获得正确的数据，这是我在那里的副本：（请注意，temp1 是垃圾，只有 temp2 和 temp3 应该保留）
--------------------------------------------------------------------
这次你将被迫编译模块。安装源代码和程序
apt-get install lm-sensors lm-sensors-source
The upstream lm-sensors maintainers know of a problem using
lm-sensors with IBM ThinkPad computers, resulting in
firmware corruption. If you are installing this package on
a ThinkPad, you should wait until the upstream maintainers
have solved this problem before building modules from it.
For more information, see
/usr/share/doc/lm-sensors-source/README.thinkpad.
IBM ThinkPad brokenness -- really install lm-sensors?
cd /usr/src
tar xzvf lm-sensors.tar.gz
cd modules/lm-sensors/
make && make install
然后你应该让 modutils 接受一些参数，最好的方法可能是使用一个新文件，例如：/etc/modutils/sensors，内容如下
alias char-major-89 i2c-dev
options it87 temp_type=0x31
update-modules
modprobe i2c-isa it87
你现在可以输入 sensors 来访问信息（请注意，你应该编辑 sensors.conf，否则你会看到奇怪和不准确的东西 :]）
你也可以把 i2c-isa 和 it87 放在 /etc/modules 中（每行一个！）以便在启动时自动加载它们，我还不清楚是否可以使用 /etc/modules.conf 进行一些自动加载/删除过程

如果你还没有挂载 sysfs 伪文件系统。
mount -t sysfs sysfs /sys
请参阅内核源代码树中的 Documentation/filesystems/sysfs.txt 和 Documentation/i2c/sysfs-interface
modprobe it87
modprobe i2c-isa 传感器可以在 sysfs 伪文件系统中访问。但是如果你想，你可以使用 lm_sensors 用户工具...
安装 sensors 用户工具
cd lm_sensors-2.8.3
将此复制到一个名为 chips-it87.diff 的文件中
注意： 此补丁仅适用于旧版本的 lm_sensors，Paolo 写道
“lm_sensors 开发人员的回复说，下一个版本的 lm_sensors 将修复此问题。它已经在 CVS 中修复了。”
