Microcontroller Based Automatic Solar Panel Direction

Abstract

Solar panel is used to store energy and use it for domestic applications. Through solar panel, light energy is converted into electric energy and stored in chargeable batteries. Apart from that, a light sensor is used to sense the direction of intense light. The microcontroller analyses the signal and accordingly it controls the motor through driver section to rotate the solar panel. Thus the voltage produced will be almost constant and the voltage is stored in a rechargeable battery. A moisture sensor is connected in the land to check the soil condition. If the water moisture is less, the sensor sends signal to the microcontroller. The pump motor supplies the necessary water to the land. If the moisture is enough, the micro controller will automatically stop the pump motor. The microcontroller program is written in assembly language. The microcontroller used is PIC 16F877A.
