Agricultural Water Saving Irrigation Controller

Abstract

Agricultural irrigation uses considerable volumes of water, and is one of the largest groups of consumptive water uses in the state. The water efficiency practices listed in this fact sheet describe how to reduce excess water use through implementation of efficient irrigation technology, effective irrigation scheduling, and soil moisture determination and retention. These practices are designed to minimize water losses from evaporation, deep percolation and runoff. Current research proposed an Embedded System for the Automatic Control of Agricultural Controller. This project has wired sensor network for the real time sensing and controlling of irrigation system. There is a need to develop new indigenous irrigation controller to improve farm productivity and input use efficiency of water and other nutrients. This paper has real time sensing and control of an irrigation system. When the condition of watering the agricultural farm is abnormal then the system automatically switches ON the motor. When the water level reaches normal level the motor automatically switch OFF. In this project we are interfacing microcontroller through temperature sensor, humidity sensor and also interfacing to GSM through MAX 232. This paper presents the design and development of Irrigation controller System built around a microcontroller. The system consists of microcontroller, peripherals including RTC, LCD and driver circuit relay to switch on/off a motor. Different parameters i.e. soil moisture, water contents, intensity, humidity, wind speed, temperature etc. The key objective of this paper is to report on a developed indigenous low cost time based microcontroller based irrigation scheduler which performs user defined functions and outputs commands to derive appropriate actuators (solenoid valves, motor).
