Embedded solar tracking instrumentation system

This paper describes the embedded solar tracking instrumentation system by using Atmega32 microcontroller. The system consists of Light Dependent Resistor (LDR) sensor, DC motor and Xbee wireless system. Atmega32 microcontroller is the main component for controlling the system. The solar system will track the location of the sun to ensure the solar panel is always perpendicular with the sun therefore optimizing power output. The operation of the system on sunny and bad weather condition has been presented in this paper. The solar tracking prototype has been stated for future works.
