A Sensor project can be installed over the air. In the emulator window, select View > External Events Generator, and select the Sensors tab. In this tab you can view all sensors currently available in the emulator, with the sensor ID, name, and availability. If the sensor supports change to availability you can click on the check box to change it. As mentioned earlier, the provided implementation does not support availability change, but a custom implementation you create might do so.
When you select a sensor row the bottom of the dialog displays any custom sensor controls. For example, the acceleration sensor, has three channels: axis_x, axis_y, and axis_z. Each channel has a slider that changes the current channel value, and an edit box you can use to input a value. The channel unit label is displayed on the far right.
Under the channels there is script player control that allows you to play sensor value events from a script file of the format discussed in Creating a Sensor Script File. See SensorBrowser for a description of how to use the Sensors demo.
