LinearAccelerationSensor.z

The z read-only property of the LinearAccelerationSensor interface returns a double precision integer containing the acceleration of the device along the device's z axis.

If a feature policy blocks use of a feature it is because your code is inconsistent with the policies set on your server. This is not something that would ever be shown to a user. See Feature-Policy for implementation instructions.

Syntax

var zAcceleration = accelerometer.z

Value

A Number.

Example

Linear acceleration is typically read in the Sensor.onreading 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();
