Streetlights are necessary for an urban area. However, there is no an effective monitoring system to maintain their functions for normal operating. Power outages occur frequently in the mountain area whenever a typhoon or earthquake strikes. For the purpose of energy saving, emergency lighting and monitoring, we proposes an LED-light monitoring system, which combines an MSP430 microcontroller, solar cells and various sensing elements with a Zigbee radio transmission. We hope to enhance the performance efficiently in the management and maintenance of streetlights. This can be done by changing the luminance intelligently and providing emergency lighting in times of power outages. A software VB is used to integrate with AJAX; and Google Map API is used in the display screen to monitor the status of various streetlights through computer networks.
