Windows PowerShellは値を出力しないことがあります（温度センサー）

Question

時々、温度センサーが表示されません。私はPowershellを使って値を読み取っています。私はWindowsが何も返さないことがある理由を知りたいです。それは私のラップトップ、ソフトウェア、または何ですか？

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

Answer 1

実際のクラスは、MSAcpi_ThermalZoneTemperatureです。

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" 
} 

オルタナティブ：

$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 
}
