First, make sure you have the Capawesome npm registry set up. You can do this by running the following commands: `[](#%5F%5Fcodelineno-0-1)npm config set @capawesome-team:registry https://npm.registry.capawesome.io [](#%5F%5Fcodelineno-0-2)npm config set //npm.registry.capawesome.io/:_authToken ` **Attention**: Replace `` with the license key you received from Polar. If you don't have a license key yet, you can get one by becoming a [Capawesome Insider](https://capawesome.io/insiders/). Next, you can use our **AI-Assisted Setup** to install the plugin. Add the [Capawesome Skills](https://github.com/capawesome-team/skills) to your AI tool using the following command: `[](#%5F%5Fcodelineno-1-1)npx skills add capawesome-team/skills --skill capacitor-plugins ` Then use the following prompt: `` [](#%5F%5Fcodelineno-2-1)Use the `capacitor-plugins` skill from `capawesome-team/skills` to install the `@capawesome-team/capacitor-barometer` plugin in my project. `` If you prefer **Manual Setup**, install the plugin by running the following commands and follow the platform-specific instructions below: `[](#%5F%5Fcodelineno-3-1)npm install @capawesome-team/capacitor-barometer [](#%5F%5Fcodelineno-3-2)npx cap sync ` ### Android[ΒΆ](#android "Permanent link") #### Proguard[ΒΆ](#proguard "Permanent link") If you are using Proguard, you need to add the following rules to your `proguard-rules.pro` file: `[](#%5F%5Fcodelineno-4-1)-keep class io.capawesome.capacitorjs.plugins.** { *; } ` ### iOS[ΒΆ](#ios "Permanent link") #### Privacy Descriptions[ΒΆ](#privacy-descriptions "Permanent link") Add the `NSMotionUsageDescription` key to the `ios/App/App/Info.plist` file, which tells the user why your app needs access to the user's contacts: `[](#%5F%5Fcodelineno-5-1)NSMotionUsageDescription [](#%5F%5Fcodelineno-5-2)The app needs to access the motion activity. ` ## Usage[ΒΆ](#usage "Permanent link") `[](#%5F%5Fcodelineno-6-1)import { Barometer } from '@capawesome-team/capacitor-barometer'; [](#%5F%5Fcodelineno-6-2) [](#%5F%5Fcodelineno-6-3)const getMeasurement = async () => { [](#%5F%5Fcodelineno-6-4) const { measurement } = await Barometer.getMeasurement(); [](#%5F%5Fcodelineno-6-5) console.log('Pressure:', measurement.pressure, 'hPa'); [](#%5F%5Fcodelineno-6-6) console.log('Relative Altitude:', measurement.relativeAltitude, 'm'); [](#%5F%5Fcodelineno-6-7) console.log('Timestamp:', new Date(measurement.timestamp)); [](#%5F%5Fcodelineno-6-8)}; [](#%5F%5Fcodelineno-6-9) [](#%5F%5Fcodelineno-6-10)const isAvailable = async () => { [](#%5F%5Fcodelineno-6-11) const result = await Barometer.isAvailable(); [](#%5F%5Fcodelineno-6-12) console.log('Barometer is available:', result.isAvailable); [](#%5F%5Fcodelineno-6-13)}; [](#%5F%5Fcodelineno-6-14) [](#%5F%5Fcodelineno-6-15)const startMeasurementUpdates = async () => { [](#%5F%5Fcodelineno-6-16) Barometer.addListener('measurement', (event) => { [](#%5F%5Fcodelineno-6-17) console.log('New measurement:', event); [](#%5F%5Fcodelineno-6-18) }); [](#%5F%5Fcodelineno-6-19) await Barometer.startMeasurementUpdates(); [](#%5F%5Fcodelineno-6-20)}; [](#%5F%5Fcodelineno-6-21) [](#%5F%5Fcodelineno-6-22)const stopMeasurementUpdates = async () => { [](#%5F%5Fcodelineno-6-23) await Barometer.stopMeasurementUpdates(); [](#%5F%5Fcodelineno-6-24) Barometer.removeAllListeners(); [](#%5F%5Fcodelineno-6-25)}; [](#%5F%5Fcodelineno-6-26) [](#%5F%5Fcodelineno-6-27)const checkPermissions = async () => { [](#%5F%5Fcodelineno-6-28) const status = await Barometer.checkPermissions(); [](#%5F%5Fcodelineno-6-29) console.log('Barometer permission status:', status.barometer); [](#%5F%5Fcodelineno-6-30)}; [](#%5F%5Fcodelineno-6-31) [](#%5F%5Fcodelineno-6-32)const requestPermissions = async () => { [](#%5F%5Fcodelineno-6-33) const status = await Barometer.requestPermissions(); [](#%5F%5Fcodelineno-6-34) console.log('Barometer permission status after request:', status.barometer); [](#%5F%5Fcodelineno-6-35)}; ` ## API[ΒΆ](#api "Permanent link") * [getMeasurement()](#getmeasurement) * [isAvailable()](#isavailable) * [startMeasurementUpdates()](#startmeasurementupdates) * [stopMeasurementUpdates()](#stopmeasurementupdates) * [checkPermissions()](#checkpermissions) * [requestPermissions()](#requestpermissions) * [addListener('measurement', ...)](#addlistenermeasurement-) * [removeAllListeners()](#removealllisteners) * [Interfaces](#interfaces) * [Type Aliases](#type-aliases) ### getMeasurement()[ΒΆ](#getmeasurement "Permanent link") `[](#%5F%5Fcodelineno-7-1)getMeasurement() => Promise ` Get the latest measurement.
