The Light Sensor module allows you to view the amount of light detected by the CPB built-in ALS-PT19 light sensor.

Luminance Reading

The current light level is displayed as a numeric value on the Luminance Reading panel at the bottom of the screen. New values are sent from the CPB ten times per second.

Try shining a flashlight on the CPB to see the values change in realtime.
