Accelerometer

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

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

Functions

Get Acceleration on X, Y, Z axes

You can get the values for xAcceleration, yAcceleration and zAcceleration at any time with the following blocks.

Properties

Enabled

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

Sensitivity

You can use the Sensitivity blocks to set the sensitivity of the Accelerometer and get its current level of sensitivity.

Property	Type	Default
set Sensitivity	one of [low, medium, high]	low
get Sensitivity	one of [low, medium, high]
