在python中访问CPU温度
我需要一个在python中访问CPU温度的示例代码 顺便说一句，我正在运行windows 7。查看库 编辑：在windows上，您可以使用python转换此文件，该文件使用WMI。您可以使用此文件访问本机windows API。我认为，如果主板驱动程序的制造商通过其驱动程序注册WMI数据提供程序，则应该可以查询Windows API的CPU温度。假设是这种情况，您可以下载ars在回答中提到的和，然后按照以下步骤进行：在python中访问CPU温度,python,windows,cpu,temperature,Python,Windows,Cpu,Temperature,我需要一个在python中访问CPU温度的示例代码 顺便说一句，我正在运行windows 7。查看库 编辑：在windows上，您可以使用python转换此文件，该文件使用WMI。您可以使用此文件访问本机windows API。我认为，如果主板驱动程序的制造商通过其驱动程序注册WMI数据提供程序，则应该可以查询Windows API的CPU温度。假设是这种情况，您可以下载ars在回答中提到的和，然后按照以下步骤进行： import wmi w = wmi.WMI() print w.Win32_

eadmaster提供的代码可能适用于OpenHardwareMonitor编程使用的旧CPU，但我有一个Skylake i7 6700K CPU。OpenHardwareMonitor没有为我提供任何结果。然而，这个程序的一个分支叫做，它基于OpenHardwareMonitor，它可以识别我的CPU 在研究如何通过Python获得CPU温度时，我切换到IronPython，以便访问.Net framework并轻松访问其他性能数据，但要想找到如何将其重新安装到普通Python 2.7中应该相当容易（只需运行CPU温度计而不是PenhardwareMonitor，并将名称空间更改为“root\cputhermeter”？有那么简单吗？） 样本输出：

我艰难地发现，查询不是很标准的SQL，并且不喜欢“ORDERBY”子句，因此我必须进行一些奇特的字符串格式设置，以便在查询以相反顺序返回核心时获得正确的顺序。这让我有点困惑，直到我想出了解决这个问题的办法 下载并解压缩OpenHardwareMonitorLib.dll和CPutherMeterlib.dll，并将它们放在一个目录中 然后，您可以使用pythonnet模块来寻址.dll并提取这些程序提供的任何stat。CPuthermeter提供每个核心的CPU温度，openhardwaremonitor提供其他一切。不需要使用要求程序在后台处于活动状态的WMI 我已经编写了一个小脚本（Python3.6.5）来显示系统上可用的每个温度传感器，您当然可以轻松地为其他传感器类型修改此脚本。您必须以管理员身份运行：

由于它以JSON格式返回数据，因此您应该可以轻松获取所需特定硬件的数据。似乎不支持Windows操作系统。它告诉我我的硬件不受支持：/python可能不是适合您需要的好语言选择。我在第一个代码中遇到以下错误：Traceback（最后一次调用）：文件“”，第244行，在run_nodebug文件“”，第3行，在indexer中。错误：列表索引超出范围我收到一系列错误（OLE/COM）尝试这两种方法时。知道原因吗？我缺少什么？如何导入OpenHardwareMonitor或CPutherMeter？我按照所有说明操作，它只是告诉我它们都不存在“OpenHardwareMonitorLib.dll和CPutherMeterlib.dll，并将它们放在一个目录中”然后，您需要使用clr.AddReference（dll）导入这些dll。这将允许您导入OHM命名空间。如果它不起作用，则dll或您的系统会出现问题，阻止加载dll。似乎是“cputhermeterlib.dll”现在使用OpenHardwareMonitor命名空间。使用JetBrains dotPeek打开两个dll文件并对它们进行比较。快速浏览后，它们看起来很相似。结果是“从CPutherMeter导入硬件”将不再存在
