## Enum Values

### BQM3

```
val NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum.BQM3: NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum
```

Becquerels per cubic meter.

### MGM3

```
val NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum.MGM3: NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum
```

Milligrams per cubic meter.

### NGM3

```
val NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum.NGM3: NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum
```

Nanogram per cubic meter.

### PM3

```
val NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum.PM3: NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum
```

Particles per cubic meter.

### PPB

```
val NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum.PPB: NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum
```

Parts per billion.

### PPM

```
val NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum.PPM: NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum

## Public functions

### toDescription

```
@HomeExperimentalGenericApi
fun toDescription(): String
```

### valueOf

```
fun valueOf(value: String): NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum
```

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

| Throws |
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-illegal-argument-exception/index.html` | if this enum type has no constant with the specified name |

### values

```
fun values(): Array<NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum>
```

Returns an array containing the constants of this enum type, in the order they're declared.

This method may be used to iterate over the constants.

## Public properties

### entries

```
val entries: EnumEntries<NitrogenDioxideConcentrationMeasurementTrait.MeasurementUnitEnum>
```

Returns a representation of an immutable list of all enum entries, in the order they're declared.

This method may be used to iterate over the enum entries.

### traitId

```
open val traitId: String
```

Trait identifier of the Matter Cluster that defines the enum Data Type. Refer to `https://developers.home.google.com/reference/kotlin/com/google/home/matter/serialization/ClusterId#traitId()` for the format.

### typeName

```
open val typeName: String
```

Name of the Matter Data Type that the enum belongs to, in UpperCamelCase, e.g. "AlarmCodeEnum" from Door Lock Cluster.

### value

```
open val value: ULong
```

Integer identifier of the enum value per the Matter Application Clusters spec, e.g. 1 for Door Lock Cluster AlarmCodeEnum.LockFactoryReset.
