lm-sensors如何理解尤其是in0~ in6、3VSB和 的输出Vbat？
答案1
不同的硬件组合可能会有所不同。最好查看 BIOS/EFI 的传感器信息（它应该是正确的），然后尝试将它们与 的输出进行比较sensors。
我不确定“适配器：虚拟设备”，它看起来类似于 CPU 或 GPU 核心。
“coretemp-isa-0000” 有 4 个核心，看起来像一个 4 核 CPU。
最后一个“it8728-isa-0a30”看起来像主板传感器。我不确定每个传感器的具体含义，除了 V 之外还有电压、风扇转速 RPM，不知道温度传感器的具体位置。这时将它们与 BIOS 进行比较可能会很有用。
网页搜索“it8728-isa-0a30”本页介绍“Gigabyte B75-D3V” 可能会有更好的描述/标签。我思考将其放在 /etc/sensors.d/ 中的文件中（然后可能需要重新启动，或者至少sudo service kmod stop重新sudo service kmod start启动传感器模块？）。
请参阅sensors和sensors.conf手册页
以下是从上面的 Gigabyte 链接粘贴的文件，尽管它确实不是看起来与您的主板相匹配，如果您想自己写标签，它可能会很有用：
