Zigbee-based intelligent street lighting system

A novel scheme for a Zigbee-based street light control is proposed with an aim to reduce the human error in the operation of street lights, decrease the energy consumption of the system, and ease the maintenance of the street light network. These objectives are achieved by creating a wireless Zigbee network of street lights that can be monitored from a base station. A new scheme that provides for the operation of alternate lights during low traffic hours, dusk and dawn has been devised. Additionally, an automatic mode of operation that utilizes light sensors to automatically switch ON street lights when light intensity falls below a certain level, has also been incorporated. The scheme was implemented, and a small scale working model was developed.
