lm_sensors
通过lm_sensors工具可以显示传感器数据，但是不同设备传感器配置也不同，如果传感器比较完备可能获取到风扇转速、温度和功率数值，如果没有的话自然没有数值
安装
探测传感器
yum install -y lm_sensors
使用
sensors-detect
显示结果例如：
# sensors-detect revision 3.4.0-8 (2016-06-01)
# System: Centerm C92 [1*V1.*]
# Kernel: 3.10.0-1160.el7.x86_64 x86_64
# Processor: Intel(R) Celeron(R) CPU J1900 @ 1.99GHz (6/55/8)
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
