## Class Properties

### Local Class Properties

Name | Data Type | Default Value | Qualifiers
--- | --- | --- | ---
Name | Data Type | Value
CurrentState | string |
Description | string | The current state indicated by the Sensor. This is always one of the "PossibleStates".
MaxLen | uint32 | 128
OtherSensorTypeDescription | string |
Description | string | A string describing the Sensor type - used when the SensorType property is set to "Other".
MaxLen | uint32 | 128
ModelCorrespondence | string | CIM_Sensor.SensorType
PollingInterval | uint64 |
Description | string | The polling interval that the Sensor hardware or the instrumentation uses to determine the current state of the Sensor.
PUnit | string | second * 10^-9
Units | string | NanoSeconds
SensorContext | string |
Description | string | SensorContext indicates the purpose and context of the sensor. For example, the property may indicate what entity is being monitored or where the sensor is installed. Contextual and location information should be provided using associations to existing model elements. This property may be used if additional differentiation is necessary beyond that which is possible to convey using associations or values of SensorType. The value shall be formatted using the following algorithm: <OrgID>:<LocalID> Where <OrgID> and <LocalID> are separated by a colon (:), and where <OrgID> shall include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the SensorContext or that is a registered ID assigned to the business entity by a recognized global authority. In addition, to ensure uniqueness, <OrgID> shall not contain a colon (:). <LocalID> is chosen by the business entity and should not be reused to identify different underlying (real-world) elements.
Experimental | boolean | true
SensorType | uint16 |
Description | string | The Type of the Sensor, e.g. Voltage or Temperature Sensor. If the type is set to "Other", then the OtherSensorType Description can be used to further identify the type, or if the Sensor has numeric readings, then the type of the Sensor can be implicitly determined by the Units. A description of the different Sensor types is as follows: A Temperature Sensor measures the environmental temperature. Voltage and Current Sensors measure electrical voltage and current readings. A Tachometer measures speed/revolutions of a Device. For example, a Fan Device can have an associated Tachometer which measures its speed. A Counter is a general purpose Sensor that measures some numerical property of a Device. A Counter value can be cleared, but it never decreases. A Switch Sensor has states like Open/Close, On/Off, or Up/Down. A Lock has states of Locked/Unlocked. Humidity, Smoke Detection and Air Flow Sensors measure the equivalent environmental characteristics. A Presence Sensor detects the presence of a PhysicalElement. A Power Consumption Sensor measures the instantaneous power consumed by a managed element. A Power Production Sensor measures the instantaneous power produced by a managed element such as a power supply or a voltage regulator. A pressure sensor is used to report pressure. Intrusion sensor reports an intrusion of an enclosure regardless whether it was authorized or not.

Values | string | Unknown, Other, Temperature, Voltage, Current, Tachometer, Counter, Switch, Lock, Humidity, Smoke Detection, Presence, Air Flow, Power Consumption, Power Production, Pressure, Intrusion, DMTF Reserved, Vendor Reserved
PossibleStates | string[] |
Description | string | PossibleStates enumerates the string outputs of the Sensor. For example, a "Switch" Sensor may output the states "On", or "Off". Another implementation of the Switch may output the states "Open", and "Close". Another example is a NumericSensor supporting thresholds. This Sensor can report the states like "Normal", "Upper Fatal", "Lower Non-Critical", etc. A NumericSensor that does not publish readings and thresholds, but stores this data internally, can still report its states.
