Ambient Light Sensor


Ambient light photo sensors detect the amount of light present within an environment, sending a signal proportional to the amount of light detected to control backlighting and basic on/off light control.

This specific reference design utilizes a dual-purpose IC from Silicon Labs which offers ambient light sensing and proximity sensing capabilities in a single device. This exceptionally small integrated sensor provides ease of implementation as it eliminates the design effort required for separate solutions.
