Windows平台下psutil风扇转速与温度模块替代方案咨询

1. OpenHardwareMonitorLib #

通过Python调用OpenHardwareMonitor的库可稳定获取硬件温度与风扇数据，步骤如下：

• 下载OpenHardwareMonitor安装包，找到OpenHardwareMonitorLib.dll文件
• 安装pythonnet库加载DLL：pip install pythonnet
• 示例代码：

import clr

# 替换为你的OpenHardwareMonitorLib.dll路径
clr.AddReference(r'C:\Program Files\OpenHardwareMonitor\OpenHardwareMonitorLib.dll')
from OpenHardwareMonitor.Hardware import Computer

def get_hardware_status():
    computer = Computer()
    # 启用需要监控的硬件类型
    computer.CPUEnabled = True
    computer.GPUEnabled = True
    computer.FanControllerEnabled = True
    computer.HDDEnabled = True
    computer.Open()

    for hardware in computer.Hardware:
        hardware.Update()
        print(f"硬件名称: {hardware.Name}")
        for sensor in hardware.Sensors:
            if sensor.SensorType == sensor.SensorType.Temperature:
                print(f"  温度传感器: {sensor.Name} - {sensor.Value}°C")
            elif sensor.SensorType == sensor.SensorType.Fan:
                print(f"  风扇: {sensor.Name} - {sensor.Value} RPM")
        print()

    computer.Close()

if __name__ == "__main__":
    get_hardware_status()

2. PySMBIOS #

专注读取系统BIOS信息，部分硬件的温度数据可通过SMBIOS获取：

• 安装依赖：pip install pysmbios
• 示例代码：

from smbios import SMBIOS

def get_smbios_temperature():
    smbios = SMBIOS()
    for info in smbios:
        if info.type == 28:  # 匹配温度传感器类型
            print(f"传感器名称: {info.designation}")
            print(f" 当前温度: {info.current_temperature}°C")
            print(f" 阈值温度: {info.threshold}°C")
            print()

if __name__ == "__main__":
    get_smbios_temperature()

局限性：并非所有硬件都支持通过SMBIOS暴露数据，风扇转速大概率无法获取

3. LM Sensors（仅Linux系统） #

Linux平台下的老牌硬件监控工具，可直接读取传感器数据：

• 先安装系统工具包（Debian/Ubuntu）：sudo apt install lm-sensors
• 安装Python库：pip install pysensors
• 示例代码：

import sensors

def get_linux_hardware_data():
    sensors.init()
    try:
        for chip in sensors.iter_detected_chips():
            print(f"芯片: {chip}")
            for feature in chip:
                if 'temp' in feature.label.lower():
                    print(f"  温度: {feature.label} - {feature.get_value()}°C")
                elif 'fan' in feature.label.lower():
                    print(f"  风扇转速: {feature.label} - {feature.get_value()} RPM")
            print()
    finally:
        sensors.cleanup()

if __name__ == "__main__":
    get_linux_hardware_data()
