Light Sensor

Measure ambient light level in lux (lx)

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

  • Light Sensor block

Simulink Support Package for Android Devices / Sensors


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


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

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

Data Types: single


expand all

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


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