Implementation of Smart LED Controller for Streetlight

In this paper we have presented a smart LED street lightening system to replace existing traditional lightening system. The proposed system is developed around ZigBee protocol which is an emerging ubiquitous sensor network(USN) technology. In this system a single node consists of an LED mounted on top of a controller, to which a number of sensors are wirelessly connected. Depending upon the illumination of LED. In order to communicate with other smart LED's each controller is connnected with all other nodes so that a node can adjust its state according to the state of its surrounding nodes. In order to verify out proposed system in real time we have built the system using mcu and implemented in our institution. Other components of the proposed system are: LED module, power driver board, main controller board, and ambient sensor board
