-====== Sensors ======
-//(Information and examples taken from the DroidScript documentation)//
-===== Description =====
-Create Sensor objects using the **CreateSensor** function of the **[[built_in:app|app]]** object:
-<code>sns = app.CreateSensor( type, options );</code>
-Types available are:
-  * **"Accelerometer"**
-  * **"MagneticField"**
-  * **"Orientation"**
-  * **"Light"**
-  * **"Proximity"**
-You can use the **SetOnChange** function of the Sensor to set the name of a function you want to be called when a the changes occur.
-Change the rate that a sensor checks for changes by adding one the options **"Fastest"**, **"Fast"**, **"Medium"** or **"Slow"**.
-"Slow" is the default.
-===== Methods =====
-Some controls use the same methods.\\
-For examples of the **[[same methods]]** look here.
