Abstract

Roads and their lighting systems are important facilities of local municipals. Most conventional street lighting systems are switched on/off at regular intervals of time. The consequence is that a large portion of electrical energy consumed by the street lighting is wasted meaninglessly if the road traffic is low. With the increasing interest in the global energy consumption and green environment requirement, automated street lighting system raises much interest around the world. In this paper, a cost effective and energy efficient automated street light control based on microcontroller and ZigBee wireless network is proposed. The street lamps are automatically controlled with the ambient light conditions, the road pedestrian and vehicle traffic conditions, and the neighbor traffic conditions.DOI:http://dx.doi.org/10.11591/ijece.v4i5.6446

Abstract

The world today uses more energy than ever before. As a global society we must find more renewable and efficient sources to obtain our energy. One of these sources might come in the form of something that we interact with everyday, the sun. Photovoltaic solar cells are a growing market in the renewable energy sector. Basic PV cell materials are discussed and the PV market in the United States is analyzed; are PV solar energy systems the answer to our current and future energy needs?
