  • Light Sensor block

Libraries:
Simulink Support Package for Android Devices / Sensors

Description

Add-On Required: This feature requires the Simulink Support Package for Android Devices add-on.

Use the Light Sensor block to measure ambient light in lux (lx) from the light sensor on the Android® device.

Note

During simulation with no hardware connected, this block does nothing. For more information, see Block Produces Zeros or Does Nothing in Simulation.

Ports

Output

expand all

The block outputs the ambient light in lux (lx).

Data Types: single

Parameters

expand all

Specify a discrete time interval, in seconds, at which the block reads the light sensor of the device and outputs the data.

Note

Smaller values for Sample time require the processor to complete the same number of instructions in less time, which can cause task overruns.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"androidsensorlib/Light Sensor"

Example: add_block("androidsensorlib/Light Sensor","myModel/myBlock",MakeNameUnique="on")

Version History

Introduced in R2014a
