A prototype of digital illuminance sensor for the distributed control lighting system

When introducing the distributed control lighting system (Intelligent Lighting System), illuminance sensors' wiring is thick and complex around A/D converter. So, we manufacture prototype of illuminance sensors with A/D converter to improve this problem. The prototype sensor can use Ethernet communication, and it is easy to connect to the Intelligent Lighting System's network by using switching hub. In this study, we measure a responsiveness of the prototype sensor. And,we experiment illuminance convergence to confirm the feasibility of the target illuminance using the prototype sensor. As a result, we confirmed that the system using the prototype sensor was able to realize the target illuminance values.
