# Getting Started

The accelerometer sensor is used to measure the force of acceleration acting on the phone. The sensor reports this force for each of the three principal axes, the x axis, y axis and, the z axis. The values obtained from the sensor are in metres per second squared, $m/s^2$.

# Events

## Shaking

There may be some instances where you want to start an event by shaking your mobile device or when the mobile device is shook. There is a Shaking event that you can add to your blocks that has sensitivity levels of high, medium and low

## Accelerometer Changes

When the accelerometer sensor detects a change in the force acting on the phone the Changes event will be fired. Each time the event fires the four associated parameters will be updated.

 Parameter Type Returns xAcceleration Number Change in speed of the phone, along the x axis, in $m/s^2$ yAcceleration Number Change in speed of the phone, along the y axis, in $m/s^2$ zAcceleration Number Change in speed of the phone, along the z axis, in $m/s^2$ error String Error message from sensor

# Properties

By default the accelerometer sensor will be turned on, but you can use the Enabled property to read its current state and to change its state, i.e turn the sensor on and off.

 Property Type Default set Enabled Bool True get Enabled Bool ​
