Abstract—In this paper, we study human body detecting using PIR sensor and design LED control system based on star network topology of Zigbee. The human body detecting information using PIR sensor is transmitted to the status monitoring system, and the management system controls the LED lighting devices based on transmitted information. The information and control signals are transmitted using ...

In allusion to high electricity consumption and resource wasting of college schoolroom, this paper proposes a lighting fuzzy control system based on CC2430. The deviation and transformation rate comparing ideal illumination and the practical one has inferenced by Fuzzy Model Reference adaptive system (FMRAS), and it can compensate natural light illumination stabilizing schoolroom lighting throu...

Using of natural lighting has come into prominence in constructed buildings, especially in last ten years, under scope of energy efficiency. Natural lighting methods are one of the methods that aim to take advantage of day light in maximum level and decrease using of artificial lighting. Increasing of day light amount in buildings by using suitable methods will give optimum result in terms of c...

A simulation algorithm is proposed that predicts the lighting energy performance of manually and automatically controlled electric lighting and blind systems in private and two-person offices. Algorithm inputs are annual profiles of user occupancy and work plane illuminances. These two inputs are combined with probabilistic switching patterns, which have been derived from field data, in order t...

A photosensor is an electronic control device that adjusts the light output of a lighting system based on detected illuminance. While some photosensors simply switch lights on and off, Specifier Reports: Photosensors focuses on photosensors that are used with dimming electronic ballasts to adjust the light output of fluorescent lighting systems over a continuous range. These photosensors are mo...

1. Introduction Mitsubishi Electric offers solutions centered on security , under the brand name DIGUARD, for various customer problems in buildings, factories, public facilities , and so on. As an example, this paper describes the development of an energy saving system that coordinates security and lighting equipment. In recent years, as evidenced by revisions to the Energy Saving Law and Toky...

This paper describes a real-time beat tracking system that recognizes a rhythmic structure in real-world audio signals sampled from popular-music compact discs. Most previous beat-tracking systems dealt with MIDI signals and had difficulty in processing, in real time, audio signals containing sounds of various instruments and in tracking beats above the quarter-note level. Our system can proces...

Dancers express their feelings and moods through gestures and body movements. We seek to extend this mode of expression by dynamically and automatically adjusting music and lighting in the dance environment to reflect the dancer’s arousal state. Our intention is to offer a space that performance artists can use as a creative tool that extends the grammar of dance. To enable the dynamic manipula...

This paper introduces a fuzzy logic-based circadian lighting control system using flexibility of Light-Emitting Diode (LED) technology to synchronise artificial with (natural) Correlated Colour Temperature (CCT) characteristics. Besides for vision acuity, the Non-Imaging Forming effects affect human rhythms. Past works in spectrally tuning CCT or Spectral Power Distribution have used convention...
