Win32_TemperatureProbe class

The Win32_TemperatureProbeWMI class represents the properties of a temperature sensor (electronic thermometer).

Most of the information that the Win32_TemperatureProbe WMI class provides comes from SMBIOS. Real-time readings for the CurrentReading property cannot be extracted from SMBIOS tables. For this reason, current implementations of WMI do not populate the CurrentReading property. The CurrentReading property's presence is reserved for future use.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.

Current status of the object. Various operational and nonoperational statuses can be defined. Operational statuses include: "OK", "Degraded", and "Pred Fail" (an element, such as a SMART-enabled hard disk drive, may be functioning properly but predicting a failure in the near future). Nonoperational statuses include: "Error", "Starting", "Stopping", and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work.
