Abstract:
Sunlight is important for the growth of plants and the photosynthesis process. It is difficult for plants to get the necessary amount of sunlight due to various factors. Sunlight may get disturbed by obstacles such as buildings. In such situations it is useful for many purposes to record sunlight detected time period and to divert sunlight for the areas where there are sunlight needed plants. A system has been developed to achieve these two tasks. The system contains two main hardware components; sunlight focusing component which will reflect the sunlight to the plants and sunlight detecting component which includes three light dependent resistors which generate signals as the sunlight is detected. Sunlight focusing component has a mirror which is used as a reflector and the system is driven by two stepper motors. The signals generated by the sunlight detecting component are taken to the computer through the parallel port. Controlling software focuses and controls the mirror according to incoming signals. This paper emphasizes how successfully this system can be implemented and how it can be used in different kinds of fields.
