This diploma thesis is a presentation of the development of a sun tracking system using a microcontroller, a comparator circuit and sensors. The tracker is very simple to use and provides the option of setting the hysteresis displacement and circuitry for controlling the motor in different directions that allows for greater control flows.
The focus with this work was on keeping the production of the tracker inexpensive with intent to economically justify the investment compared to the price of a stationary system without the tracker. We were able to design a tracker with an LCD display with possibility of detailed adjustment of the sensor for a very reasonable production price. The thesis further presents the electronic control unit comprised of a microcontroller, the motor control circuit and the tracking sensor with emphasis on the design and manufacture of the circuits.
