The Win32_TemperatureProbe  WMI 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.

Properties

The Win32_TemperatureProbe class defines the following properties.

Accuracy
