GravitySensor

The GravitySensor interface of the Sensor 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 the Permissions API.

GravitySensor()

Creates a new GravitySensor object.

Inherits properties from its ancestors, Accelerometer, Sensor, and EventTarget.

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

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

Gravity is typically read in the reading 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();
