GravitySensor

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Secure context: This feature is available only insecure contexts (HTTPS), in some or allsupporting browsers.

TheGravitySensor interface of theSensor APIs provides on each reading the gravity applied to the device along all three axes.

To use this sensor, the user must grant permission to the'accelerometer' device sensor through thePermissions API. In addition, this feature may be blocked by aPermissions Policy set on your server.

Constructor

GravitySensor(): Creates a newGravitySensor object.

Instance properties

Inherits properties from its ancestors,Accelerometer,Sensor, andEventTarget.

Instance methods

GravitySensor doesn't have own methods. However, it inherits methods from its parent interfaces,Sensor andEventTarget.

Events

GravitySensor doesn't have own events. However, it inherits events from its parent interface,Sensor.

Example

Gravity is typically read in thereading event callback. In the example below this occurs sixty times a second.

let gravitySensor = new GravitySensor({ frequency: 60 });gravitySensor.addEventListener("reading", (e) => {  console.log(`Gravity along the X-axis ${gravitySensor.x}`);  console.log(`Gravity along the Y-axis ${gravitySensor.y}`);  console.log(`Gravity along the Z-axis ${gravitySensor.z}`);});gravitySensor.start();
