A PRESENTATION ON FULLY AUTOMATED

IRRIGATION SYSTEM

introduction

An automated irrigation system refers to the • An automated irrigation system refers to the operation of the system with no or just a minimum of manual intervention beside the surveillance.

• Almost every system (drip, sprinkler, surface) can • Almost every system (drip, sprinkler, surface) can be automated with help of timers, sensors or computers or mechanical appliances. It makes the irrigation process more efficient and workers can concentrate on other important farming tasks.

Automation layout

• A typical automated drip irrigation system with its parts is shown below

Soil moisture sensors

• Often, more than one sensor should be placed at a given location at varying depths

• This is referred to as a sensing location and it can give a better representation of the plant’s can give a better representation of the plant’s water uptake

Control unit

It is computer-based control system consists • It is computer-based control system consists of a combination of hardware and software that acts as a supervisor with the purpose of managing irrigation and other related practices such as fertigation and maintenance. practices such as fertigation and maintenance. Generally, the computer-based control systems used to manage irrigation systems (e.g. drip irrigation systems) can be divided into interactive systems and fully automatic systems

Control unit

Solenoid control valve

• It is an on-off control valve that either opens or closes upon receiving an electrical signal to the solenoid pilot control.

What are the Advantages of this system?

What are the Advantages of this system?

• Automation eliminates the manual operation of opening or closing valves

• Possibility to change frequency of irrigation and fertigation processes and to optimise and fertigation processes and to optimise these processes

• Adoption of advanced crop systems and new technologies, especially new crop systems that are complex and difficult to operate manually

Cont.

• Use of water from different sources and increased efficiency in water and fertiliser use

• System can be operated at night, water loss from evaporation is thus minimisedfrom evaporation is thus minimised

• Irrigation process starts and stops exactly when required, thus optimising energy requirements

disadvantages

• The systems can be very expensive

• Self-help compatibility is very low with big-scale systems, which are very complex

• Most automated irrigation systems need • Most automated irrigation systems need electricity
