Automatic Irrigation System

Abstract

Watering is the most important cultural practice and most labor intensive task in daily greenhouse operation. Watering systems ease the burden of getting water to plants when they need it. Knowing when and how much to water is two important aspects of watering process. To make the gardener works easily, the automatic plant watering system is created. There have a various type using automatic watering system that are by using sprinkler system, tube, nozzles and other. This project uses watering sprinkler system because it can water the plants located in the pots. This project uses Arduino board, which consists of ATmega328 Microcontroller. It is programmed in such a way that it will sense the moisture level of the plants and supply the water if required. This type of system is often used for general plant care, as part of caring for small and large gardens.Normally, the plants need to be watered twice daily, morning and evening. So, the microcontroller has to be coded to water the plants in the greenhouse about two times per day. People enjoy plants, their benefits and the feeling related to nurturing them. However for most people it becomes challenging to keep them healthy and alive. To accommodate this challenge we have developed a prototype, which makes a plant more self-sufficient, watering itself from a large water tank and providing itself with artificial sunlight. The pro-To type reports status of its current conditions and also reminds the user to refill the water tank. The system automation is designed to be assistive to the user. We hope that through this prototype people will enjoy having plants without challenges related to absent or forgetfulness. Bangladesh is a third world country with less economic growth. About36 %( Bangladesh) of GDP and 64% (Bangladesh)of its employment comes from agriculture. But our agricultural history is declining due to lack of irrigation facility. At the same time the existing irrigation facilities cost the government a huge amount of subsidy every year. So it’s a high time that we find an alternative way of irrigation so that our subsidy is reduced as well as people get water throughout the year. And gives birth to our project. In our project, we will be analyzing the feasibility of solar irrigation system for surface irrigation in the context of Bangladesh. Our main goal is to identify if the existing diesel run STW can be replaced by solar irrigation pump or not. RET Screen software has been used for the analysis.
