Solar Panel Automatically Tracking System Based on
Microcontroller
Abstract:
Solar Panel
Automatically Tracking System is designed based on A
T89C52 microcontroller
in
this paper
.
The system includes photosensitive sensor, A/D converter, SCM,stepping motor , drive circuit of
motor and so on. Photodiode as a light sensor
- power conversion devices, the three identical photodiodes
were placed in three directions panels were collected on the light intensity, then the light intensity will be
converted to V
oltage signal by the light sensor circuit, V
oltage signal
is put into SCM
by the ADC0809 to
convert digital signals,the SCM compare digital signals with digital signals to control motor rotation. The
system accuracy of 4 掳
, the system is simple , easy operation , high accuracy
, high speed.
