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.
