-Create Sensor objects using the CreateSensor function of the app object:+//(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> <code>sns = app.CreateSensor( type, options );</code>
-Types available are: "Accelerometer", "MagneticField", "Orientation", "Light" and "Proximity".+Types available are:  
 +  * **Accelerometer** 
 +  * **MagneticField** 
 +  * **Orientation** 
 +  * **Light** 
 +  * **Proximity** 
 +  * **Temperature** 
 +  * **GameRotation** 
 +  * **GeomagneticRotation** 
 +  * **Gravity** 
 +  * **Gyroscope** 
 +  * **HeartRate** 
 +  * **Acceleration** 
 +  * **Pressure** 
 +  * **Humidity** 
 +  * **Rotation** 
 +  * **Motion** 
 +  * **StepCounter** 
 +  * **StepDetector** 
 + 
 +Try **sns.GetNames()** which lists all the sensor information. You can probably scan for certain keywords. 
 + 
 +You can also use a sensor id number instead of the name (just in case a future sensor is added). 
 + 
 +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.
