- Method Detail
  - getNitrogenDioxideDensity
```
java.util.concurrent.CompletableFuture<java.lang.Double> getNitrogenDioxideDensity()
```
    Retrieves the nitrogen dioxide density.
    
    Returns:
    
    a future with the nitrogen dioxide density
  - getMinNitrogenDioxideDensity
```
default double getMinNitrogenDioxideDensity()
```
    return the min value for nitrogen dioxide density. overwrite if you want to change the default value.
    
    Returns:
    
    min nitrogen dioxide density
  - getMaxNitrogenDioxideDensity
```
default double getMaxNitrogenDioxideDensity()
```
    return the max value for nitrogen dioxide density. overwrite if you want to change the default value.
    
    Returns:
    
    max nitrogen dioxide density
  - getMinStepNitrogenDioxideDensity
```
default double getMinStepNitrogenDioxideDensity()
```
    return the min step value for nitrogen dioxide density. overwrite if you want to change the default value.
    
    Returns:
    
    min step nitrogen dioxide density
  - subscribeNitrogenDioxideDensity
```
void subscribeNitrogenDioxideDensity(HomekitCharacteristicChangeCallback callback)
```
    Subscribes to changes in nitrogen dioxide density.
    
    Parameters:
    
    callback - the function when nitrogen dioxide density changes
  - unsubscribeNitrogenDioxideDensity
```
void unsubscribeNitrogenDioxideDensity()
```
    Unsubscribes from changes
