SOLAR BASED AUTO IRRIGATION SYSTEM

Abstract

Agriculture is the source of living of majority for Bangladeshi and it also has a countless influence on economy of the country. This paper involves the development and formation of automatic irrigation using solar system that uses sensor that determines soil moisture by water level indicator also its pumping system that aims to deliver the needed water based on the assigned soil moisture value. We know that people do not pour the water on to the plants in their gardens when they go to vacation or often forget to water plants. As a result, there is a chance to get the plants damaged. The project we have undertaken is “Solar Based Auto Irrigation System”. This project is taken up as BANGLADESH is an agriculture oriented country and the rate at which water resources are depleting is a dangerous threat hence there is a need of smart and efficient way of irrigation. In this project we want to work with renewable energy, solar system. Because of about 40% of the population in Bangladesh having no access to electricity. Now a day’s solar energy is cheaper than electricity. This paper also discusses the prototype design of microcontroller based on water irrigation which detects a soil if watering is required then the water will be maintained at the constant level. If the specific area is irrigated too much with water, there are possibilities that the plant may die due to excessive irrigation. The proposed system uses a microcontroller basically a platform device called Microcontroller where soil moisture sensors are connected in its internal and external ports. It will deliver the needed water according to our verification on soil moisture.
