34 CIM_LogicalElement
CIM_Sensor
The CIM_Sensor class explained in Table 3-10 contains hardware devices capable of measuring the
characteristics of some physical property, for example, the temperature or voltage characteristics of
a computer system.
Table 3-10. CIM_Sensor Properties
Class Name: CIM_Sensor
Parent Class: CIM_LogicalDevice
Property Description Data Type
SensorType The type of the sensor, for example, voltage or
temperature sensor.
Values for the SensorType property are as follows:
0 Unknown
1 Other
2 Temperature sensors measure the environmental temperature.
3 Voltage sensors measure electrical voltage.
4 Current sensors measure current readings.
5 Tachometers measure speed/revolutions of a device. For example, a fan
device can have an associated tachometer that measures its speed.
6 Batteries maintain the time and date and save the system’s BIOS
configuration when the system is switched off.
uint16
OtherSensorType
Description
The type of sensor when the SensorType property is set to Other. string
PossibleStates Enumerates the string outputs of the sensor. For example, a NumericSensor
can report states based on threshold readings.
string
CurrentState Indicates the current state of the sensor. This value is always one of the
Possible States.
string
PollingInterval Indicates the polling interval, in nanoseconds, that the sensor hardware or
instrumentation uses to determine the current state of the sensor.
