Agricultural Water Saving Irrigation Controller

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).
