lm-sensors 為 Linux 提供了一個硬件健康監控驅動程序。 系統管理員使用它來檢查硬件的健康狀態。 它還用於監控服務器中的硬件基礎設施，並且在關鍵任務應用程序中非常有價值。 但是配置它以使用相對容易。 下面展示瞭如何在你的 Ubuntu/Debian 上安裝 lm 傳感器工具和 Fedora Linux 發行版。
1) 安裝
在 Ubuntu 和 Debian 發行版上
# apt install lm-sensors在 Fedora 26 和 RPM Linux 發行版
# dnf install lm_sensors安裝完成後，運行以下命令來檢查您當前的硬件規格。
# sudo sensors-detect它會問你幾個問題。 對所有人都回答是。
```
[root@localhost bin]# sensors-detect
# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# System: ASUSTeK COMPUTER INC. X540LA [1.0] (laptop)
# Kernel: 4.11.11-300.fc26.x86_64 x86_64
# Processor: Intel(R) Core(TM) i3-5020U CPU @ 2.20GHz (6/61/4)
This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): yes
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No

(driver `coretemp')
Intel AMB FB-DIMM thermal sensor... No
Intel 5500/5520/X58 thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... No
Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): yes
/dev/port: Operation not permitted
Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): yes
/dev/port: Operation not permitted
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): yes
Found unknown SMBus adapter 8086:9ca2 at 0000:00:1f.3.
Sorry, no supported PCI bus adapters found.

Next adapter: Synopsys DesignWare I2C adapter (i2c-7)
Do you want to scan it? (YES/no/selectively): yes
Adapter doesn't support all probing functions.
Some addresses won't be probed.
Next adapter: Synopsys DesignWare I2C adapter (i2c-8)
Do you want to scan it? (YES/no/selectively): yes
Adapter doesn't support all probing functions.
Some addresses won't be probed.
Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): yes
Unloading i2c-dev... OK
[root@localhost bin]#
```測試lm傳感器
最後得到你的CPU溫度類型 sensors 在您的終端中。 這測試了 lm-sensors 工具正常工作。 此外，要檢查 CPU 溫度、風扇速度和其他數據，請運行以下命令：
[root@localhost bin]# sensors
asus-isa-0000
Adapter: ISA adapter
cpu_fan: 2100 RPM
temp1: +49.0°C
acpitz-virtual-0
Adapter: Virtual device
temp1: +49.0°C (crit = +108.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Package id 0: +50.0°C (high = +105.0°C, crit = +105.0°C)
Core 0: +49.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +50.0°C (high = +105.0°C, crit = +105.0°C)
pch_wildcat_point-virtual-0
Adapter: Virtual device
temp1: +47.0°C該傳感器的輸出顯示兩個設備：asus-isa-0000（主板傳感器）和 ccoretemp-isa-0000（英特爾酷睿傳感器）。 主板傳感器設備具有有關主板（in1-6）從電源單元接收到的電壓、風扇速度（帶有 RPM 的條目）和各種內部溫度的信息。
2）安裝和自定義lm-sensor GUI：Psensor
a) 安裝 psensor
如果您不想在終端中使用 lm-sensor，您可以安裝 psensor，它是 lm-sensors 的 GUI。
在 Debian 系統上
# apt install psensor

The following additional packages will be installed:
libappindicator3-1 libdbusmenu-glib4 libdbusmenu-gtk3-4 libindicator3-7 libjson-c3 libxnvctrl0 psensor-common
The following NEW packages will be installed:
libappindicator3-1 libdbusmenu-glib4 libdbusmenu-gtk3-4 libindicator3-7 libjson-c3 libxnvctrl0 psensor psensor-common在 Redhat 系統上，默認系統存儲庫中不提供 psensor，因此您需要從源代碼編譯它。 我們首先需要安裝 wget
# dnf install wget

現在安裝了 psensor，您可以通過圖形菜單啟動它，結果如下：
您可以通過在下面取消選擇 temp1、Core1 和 ST500LT012-1DG142 的右側取消粘貼來選擇哪個元素將出現在圖表上
您可以編輯 psensor 首選項。 你可以編輯
- 喜好： 您可以在其中修改工具的啟動方式、界面或圖形表示，如下所示 磷傳感器 -> 偏好
- 傳感器首選項： 在這裡，您可以編輯 psensor 工具如何對受監控的服務進行操作，例如警報以發出通知或修改服務名稱，如下所示 磷傳感器 -> 傳感器首選項
然後你可以看到一個通知，它可以顯示如下
這 lm-sensors 是執行硬件健康檢查的非常有用的工具。 但是，由於 CLI 界面較差，大多數用戶更喜歡基於 GUI 的應用程序。 但是，lm-sensor 可以配置為使用 GUI 工具，例如 sensors-applet, psensor 這是一個 GTK 應用程序，可顯示 CPU、硬盤溫度、風扇速度等圖表。 lm-sensors 可以進一步配置為使用控制系統風扇 fancontrol 腳本。 這可以很容易地完成運行 sudo pwmconfig 命令並仔細按照說明進行操作。
