Windows Powershell 有时不输出任何值(温度传感器) [英] Windows Powershell sometimes outputs no values (temperature sensor)

问题描述

有时会发生没有温度传感器显示的情况.我使用 Powershell 来读取值并且经常工作.我想知道为什么 Windows 有时不返回任何内容.是在我的笔记本电脑、软件还是什么上?

From time to time it happens that no temperature sensors are displayed. I use Powershell to read the values and that works often. I would like to know why Windows sometimes does not return anything. Is that on my laptop, software or what?

powershell Get-WmiObject -Class Win32_PerfFormattedData_Counters_ThermalZoneInformation |Select-Object Name,Temperature

推荐答案

实际的类是 MSAcpi_ThermalZoneTemperature.使用以下函数:

The actual class is MSAcpi_ThermalZoneTemperature. Use the below function:

function Get-Temperature {
    $t = Get-WmiObject MSAcpi_ThermalZoneTemperature -Namespace "root/wmi"
    $currentTempKelvin = $t.CurrentTemperature / 10
    $currentTempCelsius = $currentTempKelvin - 273.15
    $currentTempFahrenheit = (9/5) * $currentTempCelsius + 32
    return $currentTempCelsius.ToString() + " C : " + $currentTempFahrenheit.ToString() + " F : " + $currentTempKelvin + "K" 
}

替代方案:

$strComputer = "."

$objWMi = get-wmiobject -namespace root\WMI -computername localhost -Query "Select * from MSAcpi_ThermalZoneTemperature"

foreach ($obj in $objWmi)
{
    write-host "Active:" $obj.Active
    write-host "ActiveTripPoint:" $obj.ActiveTripPoint
    write-host "ActiveTripPointCount:" $obj.ActiveTripPointCount
    write-host "CriticalTripPoint:" $obj.CriticalTripPoint
    write-host "CurrentTemperature:" $obj.CurrentTemperature
    write-host "InstanceName:" $obj.InstanceName
    write-host "PassiveTripPoint:" $obj.PassiveTripPoint
    write-host "Reserved:" $obj.Reserved
    write-host "SamplingPeriod:" $obj.SamplingPeriod
    write-host "ThermalConstant1:" $obj.ThermalConstant1
    write-host "ThermalConstant2:" $obj.ThermalConstant2
    write-host "ThermalStamp:" $obj.ThermalStamp
    write-host
    write-host "########"
    write-host
}
