A wireless managonent systean for solar street lamp based on nanoLOC AVR nttlule is researched in this paper, the system can real-timely detect the solar street lamp＇s battery voltage, corrent, tonperature, internal resistance, residual capacity and so on. And the collected data is transmitted to computer＇ s management via wireless connnunication to achieve recording, storage, analysis and processing for various parameters.展开更多
