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. In addition, this feature may be blocked by a Permissions Policy set on your server.
Constructor
GravitySensor()
-
Creates a new
GravitySensor
object.
Instance properties
Inherits properties from its ancestors, Accelerometer
, Sensor
, and EventTarget
.
Instance methods
GravitySensor
doesn't have own methods. However, it inherits methods from its parent interfaces, Sensor
and EventTarget
.
Events
GravitySensor
doesn't have own events. However, it inherits events from its parent interface, Sensor
.
Example
Gravity is typically read in the reading
event callback. In the example below this occurs sixty times a second.
js
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();
