#### Measurement

Air pressure and relative altitude values sampled from the device barometer.

| Prop | Type | Description | Since |
| ---------------------- | ------------------- | ------------------------------------------------------------------------------------------------------------------- | ----- |
| pressure | number | The static air pressure in hectopascals (hPa). | 1.0.0 |
| relativeAltitude | number | The change in altitude relative to the time updates started. Only available on iOS; Android will always return 0. | 1.0.0 |
| timestamp | number | The timestamp of the measurement in milliseconds since the Unix epoch. | 1.0.0 |


#### IsAvailableResult

Result returned by {@link CapacitorBarometerPlugin.isAvailable}.

| Prop | Type | Description | Since |
| ----------------- | -------------------- | -------------------------------------------------------- | ----- |
| isAvailable | boolean | Indicates whether the device exposes a barometer sensor. | 1.0.0 |


#### PermissionStatus

Permission information returned by {@link CapacitorBarometerPlugin.checkPermissions}
and {@link CapacitorBarometerPlugin.requestPermissions}.

| Prop | Type | Description | Since |
| --------------- | ----------------------------------------------------------------------------- | ---------------------------------------------------------------------------------- | ----- |
| barometer | BarometerPermissionState | The permission state for accessing barometer measurements on the current platform. | 1.0.0 |


#### PluginListenerHandle

| Prop | Type |
| ------------ | ----------------------------------------- |
| remove | () => Promise<void> |

#### GetMeasurementResult

Alias for the most recent pressure sample.

Measurement


#### BarometerPermissionState

Permission state union including limited` for platforms that can throttle sensor access.

PermissionState | 'limited'

#### PermissionState

'prompt' | 'prompt-with-rationale' | 'granted' | 'denied'

#### MeasurementEvent
