Accelerometer
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,
.
The x, y and z axes of a standard smartphone
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
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 |
yAcceleration | Number | Change in speed of the phone, along the y axis, in |
zAcceleration | Number | Change in speed of the phone, along the z axis, in |
error | String | Error message from sensor |
You can get the values for xAcceleration, yAcceleration and zAcceleration at any time with the following blocks.
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 | |
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] | |
