Apache Cordova | Phonegap Accelerometer tutorial with example (Device Motion)

What is accelerometer ?

Accelerometer is a feature where you can capture device motion in the x, y, and z direction.

About Sensor

An accelerometer is an electromechanical device used to measure acceleration forces. Such forces may be static, like the continuous force of gravity or, as is the case with many mobile devices, dynamic to sense movement or vibrations. Acceleration is the measurement of the change in velocity, or speed divided by time.

Accelerometer in phonegap

We can also capture device motion with phonegap-device-motion plugin

phonegap device motion plugin installation

cordova plugin add org.apache.cordova.device-motion

There are three methods in device-motion (Accelerometer) plugin such as

getCurrentAcceleration – returns current acceleration

watchAcceleration – continuously watch acceleration

clearWatch – clear all

function onSuccess(acceleration) {
    alert('Acceleration X: ' + acceleration.x + '\n' +
          'Acceleration Y: ' + acceleration.y + '\n' +
          'Acceleration Z: ' + acceleration.z + '\n' +
          'Timestamp: '      + acceleration.timestamp + '\n');
function onError() {
var options = { frequency: 3000 };  // Update every 3 seconds
var watchID = navigator.accelerometer.watchAcceleration(onSuccess, onError, options);

    its not working
    should i add any js file to it like cordova.js

    • http://www.phonegappro.com Sundara Vel

      Actaually, No need to add any file, if it is not working means , try to add js folder from device motion plugin

      • muneesh

        thank you i will try it

        • http://www.phonegappro.com Sundara Vel

          Working ah?

          • muneesh

            i had sent you a mail please have a look at it

      • muneesh

        i tried adding the files acceleration.js & accelerometer.js from device motion plugin.
        still its not working
