Automated Irrigation System Using IOT and Raspberry Pi

Abstract

Irrigation is the process of artificially supplying water to land where crops are cultivated. Traditionally hand pumps, canal water and rainfall were a major source of water supply for irrigation. This method has led to severe drawbacks like underirrigation, over-irrigation which in turn causes leaching and loss of nutrient content of soil. Changing environmental conditions and shortage of water have led to the need for a system which efficiently manages irrigation of fields. Automated irrigation system is a useful machine based system, which automates the irrigation of land by combining various software and hardware approaches together for field irrigation. Automation is increasing day-by-day in home and office. It makes an efficient use of the electricity and water and reduces much of the wastage. Currently the automation is one of the important role in the human life. It not only provides comfort but also reduce energy, efficiency and time saving. Now the industries are use automation and control machine which is high in cost and not suitable for small scale plants. So here we design a smart irrigation technology in low cost which is usable. In areas like office premises, buildings, house gardens etc. where watering plants at regular interval matters, the proposed irrigation system will be very efficient. The paper presents a home automation system which is based on Raspberry pi and relay boards to water plants. The aim is to develop a smart irrigation monitoring system using raspberry pi. We will develop such a system that will help us to know current plant status. Focus area will be parameters such as temperature and soil moisture. Raspberry pi acts as the control block in the automatic irrigation system to control the flow of motor. The commands are processed at raspberry pi. This paper presents an efficient and fairly cheap automation irrigation system. By using moisture sensor we will make the irrigation system smart and automated. System once installed has no maintenance cost and is easy to use.
