Microcontroller Based Automatic Solar Panel Direction And Irrigation Control

Abstract

Storage of energy is dangerously affecting the economic growth of the developing countries. In this project, it is proposed that efficient use of solar energy can solve the energy problem in our country and also automatic control of agricultural watering. 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 according to the direction of intensity of light, the solar panel will be rotated. 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 microcontroller operates the Pump motor. The pump motor supplies the necessary water to the land. If the moisture is enough, the microcontroller will automatically stop the pump motor. The microcontroller program is written in assembly language.
