由于我维护的服务器IDC机房空调制冷效果不好的，所以我总是有些担心温度太高把它烧掉。在网上找了找发现”lm-senwors”不光可以检测到温度信息，连电压、风扇转速也可以检测到。只不过还要看它是否支持主板上的传感器。不管怎么样，先装上试试看！

首先安装”lm-sensors”：

# aptitude install lm-sensors

运行以下命令侦测传感器：

# sensors-detect

通常都回答 yes 即可，注意最后一项：

To load everything that is needed, add this to /etc/modules:

#—-cut here—-
# Chip drivers
it87
#—-cut here—-

Do you want to add these lines automatically? (yes/NO)

这段是说找到相应的传感器”it87″，并问是否将这个传感器的驱动模块放到”/etc/modules”，让它自动加载。这个当然也是选”yes”了。

因为当前系统中还没加载这个模块，所以我们还要手动加载一下：

# modprobe it87

然后运行“sensors”就会出现 CPU 温度和电压之类的信息了。如我的显示为：

acpitz-virtual-0

temp2: +34.0°C (low = +127.0°C, high = +127.0°C) sensor = transistor
temp3: +27.0°C (low = +127.0°C, high = +65.0°C) sensor = thermal diode
cpu0_vid: +2.050 V
