According to the report, the human race is the sun, stars, has to conform to the natural light and the evolution of such month to relax and work more efficient lighting environment similar to the natural light that it is possible for hundreds of thousands of years. In addition, these reports are based on various lighting conditions, the human body and mind is the point sensitively reacts and as close to natural light and is noted that the human being can feel comfortable. Thus, the ultimate goal of future-oriented lighting can be said to provide the brightness and color temperature that are optimized for each of the living environment in accordance with human biological rhythms that conforms to the natural light to change for 24 hours.
Modbus is a serial communications protocol, it has since become a practically standard communication protocol, and it is now a commonly available means of connecting industrial electronic devices. Therefore, it can be connected with all devices using Modbus protocol to the measurement and remote control on the ships, buildings, trains, airplanes and etc..
In this paper, we add the Modbus communication protocol to the existing lighting controller sensitivity to enable verification and remote control by external environmental factors, and also introduces a fuzzy inference system was configured by external environmental factors to control LED lighting.
