Device Orientation Plugin

Tested Version: 2.0.1

This document is based on the original Cordova docs available at Cordova Docs.

This plugin provides access to the device's compass. The compass is a sensor that detects the direction or heading that the device is pointed, typically from the top of the device. It measures the heading in degrees from 0 to 359.99, where 0 is north.

Access is via a global navigator.compass object. Although the object is attached to the global scoped navigator, it is not available until after the deviceready event.

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {

Adding the Plugin in Monaca

In order to use this plugin, please enable Device Orientation plugin in Monaca Cloud IDE.

Supported Platforms

  • Android

  • iOS


  • navigator.compass.getCurrentHeading

  • navigator.compass.watchHeading

  • navigator.compass.clearWatch

Get the current compass heading. The compass heading is returned via a CompassHeading object using the compassSuccess callback function.

navigator.compass.getCurrentHeading(compassSuccess, compassError);


function onSuccess(heading) {
    alert('Heading: ' + heading.magneticHeading);

function onError(error) {
    alert('CompassError: ' + error.code);

navigator.compass.getCurrentHeading(onSuccess, onError);

Gets the device's current heading at a regular interval. Each time the heading is retrieved, the headingSuccess callback function is executed.

The returned watch ID references the compass watch interval. The watch ID can be used with navigator.compass.clearWatch to stop watching the navigator.compass.

var watchID = navigator.compass.watchHeading(compassSuccess, compassError, [compassOptions]);

compassOptions may contain the following keys:

  • frequency: How often to retrieve the compass heading in milliseconds. (Number) (Default: 100)

  • filter: The change in degrees required to initiate a watchHeading success callback. When this value is set, frequency is ignored. (Number)


function onSuccess(heading) {
    var element = document.getElementById('heading');
    element.innerHTML = 'Heading: ' + heading.magneticHeading;

function onError(compassError) {
    alert('Compass error: ' + compassError.code);

var options = {
    frequency: 3000
}; // Update every 3 seconds

var watchID = navigator.compass.watchHeading(onSuccess, onError, options);

iOS Quirks

Only one watchHeading can be in effect at one time in iOS. If a watchHeading uses a filter, calling getCurrentHeading or watchHeading uses the existing filter value to specify heading changes. Watching heading changes with a filter is more efficient than with time intervals.

Android Quirks

  • No support for filter.

Stop watching the compass referenced by the watch ID parameter.

  • watchID: The ID returned by navigator.compass.watchHeading.


var watchID = navigator.compass.watchHeading(onSuccess, onError, options);

// ... later on ...



A CompassHeading object is returned to the compassSuccess callback function.


  • magneticHeading: The heading in degrees from 0-359.99 at a single moment in time. (Number)

  • trueHeading: The heading relative to the geographic North Pole in degrees 0-359.99 at a single moment in time. A negative value indicates that the true heading can't be determined. (Number)

  • headingAccuracy: The deviation in degrees between the reported heading and the true heading (Number)

  • timestamp: The time at which this heading was determined. (DOMTimeStamp)

Android Quirks

  • The trueHeading property is not supported, but reports the same value as magneticHeading.

  • The headingAccuracy property is always 0 because there is no difference between the magneticHeading and trueHeading.

iOS Quirks

  • The trueHeading property is only returned for location services enabled via navigator.geolocation.watchLocation().


A CompassError object is returned to the compassError callback function when an error occurs.


  • code: One of the predefined error codes listed below.
