Abstract:

With MSP430F5438A as the core processor and two stepper motors as the electrical drives, an intelligent sun-tracking motion control system was designed and implemented. The time-based sun-tracking method was adopted as motion system to follow the sun and automatically reflect sun-light into a specified indoor room. The controller supports ZigBee wireless communication. With ZigBee network and a remote data server, users can manage and monitor the working mode,orientation angles,health status of the sun-tracking system via a mobile phone or a computer in remote. This sun-tracker controller has the benefits of low cost, low power consumption and high stability, applicable for use in small-scale central solar power station, sun-heated furnace, photovoltaic power station and other solar-energy applications.
