A Study on Saving Energy in Artificial Lighting by Making Smart Use of Wireless Sensor Networks and Actuators
(IEEE, 2009-12)
This article is focused on adapting lighting conditions to user lighting preferences. A theoretical analysis of lighting conditions is carried out, and a case study is shown by means of the setup of an experimental environment ...
