Sindhu posted about their ambient work light situation in this post on medium:
The purpose of Sirius is to adjust ambient lighting. Sirius controls lighting by periodically taking a photo and calculating levels of brightness in the image. Then the lamp near my desk is turned on if the ambient brightness drops. The lamp is also turned off when the brightness hits the max threshold. Why is this important to me, you ask… because I prefer working in a well lit (mostly bright) environment.
