Towards smart street lighting system in Malaysia

Smart street lighting system is one of the technologies that support green environmental related works. The technology that evolves with the advance in wireless communication and low energy street light has become the foundation in the development of smart cities. This paper presents preliminary work towards the development of a complete smart street lighting system focusing on Malaysian environment. The system integrates Wireless Sensor Network (WSN) concept in the development, utilizing Waspmote as a sensor node, Meshlium gateway and computer as a server. The sensor node can be used to monitor the running status information, amount of energy use and dimming time of the street light for data logging purposes. The developed system found to save energy through the method of controlling the light intensity using Pulse Width Modulation (PWM) technique.
