Abstract: This paper designed a solar automatic tracking controller based on single chip. The tracking controller took the single chip STC89C52 as the microcontroller to send pulses to a step motor driver. In sunny days, an ordinary silicon photocell was used for rough tracking and a PSD sensor was used for accurate tracking. When the weather condition was not good, data recorded in sunny days was used to carry out tracking. Actually measured data shows that automatic tracking controller can effectively raise the system to receive solar radiation energy, reaching preset goal.
Key words: automatic tracking; solar energy; single chip; step motor; position transducer
