Visible range light sensor useful for synchronization with visual stimuli and cues. 

The biosignalsplux Light sensor can be used for a variety of different purposes such as tracking physiological response (e.g. heart rate) in dependence of the ambient light changes or visual evoked potentials.

Another common need when working with biosignals is the synchronization of the recorded data with external sources. For instance, when applied to the computer screen, this sensor can detect chromatic changes in the screen as a possible synchronization marker.
