Lesson 5: Managing Device Sensors and Notifications

Managing Device Sensors and Notifications

1. Using Device Sensors:

   • Accelerometer:

     import { Accelerometer } from 'expo-sensors';
const [data, setData] = useState({});
useEffect(() => {
const subscription = Accelerometer.addListener(accelerometerData => {
setData(accelerometerData);
});
return () => subscription.remove();
}, []);


   • Gyroscope:

     import { Gyroscope } from 'expo-sensors';
const [data, setData] = useState({});
useEffect(() => {
const subscription = Gyroscope.addListener(gyroscopeData => {
setData(gyroscopeData);
});
return () => subscription.remove();
}, []);


2. Sending Notifications:

   import * as Notifications from 'expo-notifications';

   Notifications.scheduleNotificationAsync({
content: {
title: "Time to study!",
body: "Don't forget to complete your React Native lesson.",
},
trigger: { seconds: 5 },
});


Conclusion: Accessing device sensors and sending notifications can greatly enhance the functionality and user engagement of your app. Expo provides easy-to-use APIs for these tasks, making it simple to implement these features.
