如何在linux/unix系統中獲取CPU溫度

使用Lm_Sensors檢測cpu溫度

Lm_sensors是一個命令行工具，用於顯示所有芯片傳感器數據的當前讀數，包括CPU溫度。默認情況下，Ubuntu LInux沒有安裝Lm_Sensors，因此，我們必須自己安裝它們。

ubunntu系統中
bob@bob-PC:~$ sudo apt install lm-sensors

檢測硬件

接下來，我們需要檢測安裝在電腦上的硬件監控芯片。現在我們可以開始檢測電腦的硬件傳感器了：

bob@bob-PC:~$ sudo sensors-detect
# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# System: VMware, Inc. VMware Virtual Platform [None]
# Board: Intel Corporation 440BX Desktop Reference Platform
# Kernel: 4.15.0-30Ubuntu-generic x86_64
# Processor: Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz (6/158/10)

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

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

顯示cpu溫度

可以通過一下命令查看溫度數據了：

bob@bob-PC:~$ sensors
iwlwifi_1-virtual-0
Adapter: Virtual device
temp1:        +33.0°C  

pch_skylake-virtual-0
Adapter: Virtual device
temp1:        +38.5°C  

BAT0-acpi-0
Adapter: ACPI interface
in0:         +12.45 V  

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +38.0°C  (high = +100.0°C, crit = +100.0°C)

thinkpad-isa-0000
Adapter: ISA adapter
fan1:           0 RPM

temp7:         +0.0°C  
temp8:         +0.0°C

還可以使用watch命令實時關注：

bob@bob-PC:~$ watch sensors

使用圖形化工具psensor顯示cpu溫度

使用Psensor，您可以檢查以下各項：

• 主板、CPU傳感器和NVidia GPU的溫度
• 硬盤驅動器的溫度
• 風扇的轉速
• 監視CPU使用情況

最新版本的Psensor還為Ubuntu提供了一個applet指示器，因此在Ubuntu上更容易監控硬件溫度。您可以選擇在頂部面板中顯示溫度。它甚至可以在溫度超過極限時發送桌面通知。

我們可以使用下面的命令安裝Psensor：

bob@bob-PC:~/Desktop$ sudo apt install -y psensor

打開ubuntu的launchpad，在里面找到psensor，打開該應用就可以看到多個傳感器：

使用圖形化工具hardinfo

Hardinfo是Linux中用於在圖形化界面中顯示硬件信息的工具。可以使用它檢測cpu的溫度。以下命令安裝hardinfo：

 

bob@bob-PC:~/Desktop$ sudo apt install hardinfo
# 運行一下命令打開hardinfo
bob@bob-PC:~/Desktop$ sudo hardinfo

備注  centos 系列

yum install lm_sensors
sensors-detect
sensors

Ubuntu系列(多了service module-init-tools start一步驟)
apt-get install lm-sensors
sensors-detect
service module-init-tools start
sensors

也可以通過sys系統讀取cpu的溫度: /sys/class/hwmon/hwmon0/device/
