| Abstract: | Traffic signal controller with solar energy extremely depends on illumination of the environment. A solution which is of low-cost and low-power consumption is proposed based on MSP430 embedded in count-down traffic signal controller, and the communication network is set up using RS-232 serial port. The experimental result indicates this reliable system and ultra-low power performance may be widely applied in solar energy controllers. |
