TheLinearAccelerationSensor interface of theSensor APIs provides on each reading the acceleration applied to the device along all three axes, but without the contribution of gravity.

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

LinearAccelerationSensor()

Creates a newLinearAccelerationSensor object.

Instance properties

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

Instance methods

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

Events

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

Example

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

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