lm-sensors可以獲得主板，CPU工作電壓、溫度、風扇轉速等信息。
大多數現代主板都包含某種形式的硬體監視晶片。
這些晶片讀取諸如晶片溫度，風扇轉速和電壓電平。
有很多不同的晶片可以由主板製造商獲得大致相同的結果。

作業系統：CentOS 7.9
[root@yaomm sbin]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)安裝溫度檢測軟體：lm-sensors
yum install lm_sensors監測所有能監測的溫度傳感器
sh -c "yes|sensors-detect"安裝過程：
[root@yaomm sbin]# sh -c "yes|sensors-detect"
# sensors-detect revision 3.4.0-8 (2016-06-01)
# System: Default string Default string [Default string]
# Kernel: 3.10.0-1160.el7.x86_64 x86_64
# Processor: Intel(R) Celeron(R) CPU J1900 @ 1.99GHz (6/55/9)
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): Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
