--- title: Sensors description: A library that provides access to a device's accelerometer, barometer, motion, gyroscope, light, magnetometer, and pedometer. sourceCodeUrl: https://github.com/expo/expo/tree/main/packages/expo-sensors packageName: expo-sensors iconUrl: /static/images/packages/expo-sensors.png platforms: ["android", "ios", "web"] --- import { ConfigReactNative, ConfigPluginExample, ConfigPluginProperties, } from '~/ui/components/ConfigSection'; `expo-sensors` provide various APIs for accessing device sensors to measure motion, orientation, pressure, magnetic fields, ambient light, and step count. ## Installation ## Configuration in app config You can configure `expo-sensors` using its built-in [config plugin](/config-plugins/introduction/) if you use config plugins in your project ([EAS Build](/build/introduction) or `npx expo run:[android|ios]`). The plugin allows you to configure various properties that cannot be set at runtime and require building a new app binary to take effect. ```json app.json { "expo": { "plugins": [ [ "expo-sensors", { "motionPermission": "Allow $(PRODUCT_NAME) to access your device motion" } ] ] } } ``` ## API ```js // OR import { Accelerometer, Barometer, DeviceMotion, Gyroscope, LightSensor, Magnetometer, MagnetometerUncalibrated, Pedometer, } from 'expo-sensors'; ``` ## Permissions ### Android Starting in Android 12 (API level 31), the system has a 200Hz limit for each sensor updates. If you need an update interval of less than 200Hz, you must add the following permissions to your **app.json** inside the [`expo.android.permissions`](../config/app/#permissions) array. If you're not using Continuous Native Generation ([CNG](/workflow/continuous-native-generation/)) or you're using native **android** project manually, add `HIGH_SAMPLING_RATE_SENSORS` permission to your project's **android/app/src/main/AndroidManifest.xml**: ```xml <uses-permission android:name="android.permission.HIGH_SAMPLING_RATE_SENSORS" /> ``` ### iOS The following usage description keys are used by this library: ## Available sensors For more information, see the documentation for the sensor you are interested in:
