Class WindowsSensors

java.lang.Object

oshi.hardware.common.AbstractSensors

oshi.hardware.common.platform.windows.WindowsSensors

All Implemented Interfaces:

Sensors

@ThreadSafe
public abstract class WindowsSensors
extends AbstractSensors

Abstract base shared by the Windows Sensors implementations (JNA and FFM). Holds the Open Hardware Monitor / Libre Hardware Monitor / WMI fallback orchestration, the reflection-based Libre Hardware Monitor queries (which are backend-agnostic), and the WMI/OHM result processing. The native driver queries are provided by the subclasses.

Method Details

queryCpuTemperature

public double queryCpuTemperature()

Description copied from class: AbstractSensors

Queries the CPU temperature.

Specified by:

queryCpuTemperature in class AbstractSensors

Returns:

the CPU temperature in degrees Celsius

queryFanSpeeds

public int[] queryFanSpeeds()

Description copied from class: AbstractSensors

Queries the fan speeds.

Specified by:

queryFanSpeeds in class AbstractSensors

Returns:

an array of fan speeds in RPM

queryCpuVoltage

public double queryCpuVoltage()

Description copied from class: AbstractSensors

Queries the CPU voltage.

Specified by:

queryCpuVoltage in class AbstractSensors

Returns:

the CPU voltage in Volts

selectOhmCpuIdentifier

protected static String selectOhmCpuIdentifier(WmiResult<OhmHardware.IdentifierProperty> ohmHardware,
 boolean searchCpu)

Selects the CPU hardware identifier from an Open Hardware Monitor identifier result. When searchCpu is set, the first identifier containing cpu is used; otherwise (or if none match) the first identifier is returned.

Parameters:

ohmHardware - the OHM hardware identifier result

searchCpu - whether to search for an identifier containing cpu

Returns:

the selected identifier (possibly empty)

queryOhmCpuSensor

protected abstract WmiResult<OhmSensor.ValueProperty> queryOhmCpuSensor(String typeToQuery,
 String typeName,
 String sensorType,
 boolean searchCpu)

Queries an Open Hardware Monitor CPU sensor via the backend-specific WMI handler.

Parameters:

typeToQuery - the OHM hardware type to query

typeName - the OHM hardware type name

sensorType - the sensor type

searchCpu - whether to search for a cpu identifier (vs. using the first)

Returns:

the sensor values, or null if unavailable

queryWmiTemperature

protected abstract WmiResult<MSAcpiThermalZoneTemperature.TemperatureProperty> queryWmiTemperature()

Queries the current temperature from WMI MSAcpi_ThermalZoneTemperature.

Returns:

the WMI temperature result

queryWmiFanSpeed

protected abstract WmiResult<Win32Fan.SpeedProperty> queryWmiFanSpeed()

Queries fan speeds from WMI Win32_Fan.

Returns:

the WMI fan speed result

queryWmiVoltage

protected abstract WmiResult<Win32Processor.VoltProperty> queryWmiVoltage()

Queries CPU voltage from WMI Win32_Processor.

Returns:

the WMI voltage result
