IRRIGATION SYSTEM FOR AUTOMATIC CONTROL
Published Thursday 6 October 2011 by gk inIRRIGATION SYSTEM FOR AUTOMATIC CONTROL
Objective:
The objective of this project is to design for automatic irrigation system.
Scope:
This project is mainly used for agriculture purposes. In this project is used in real time we can also avoid excess of water flow to crop.
Brief Methodology:
This project is designed by following blocks
· Microcontroller
· Object sensor
· Driver circuit
· Relay
· Pump
In scientific irrigation scheduling water should be applied to a crop at an appropriate soil water tension to fulfil its evapotranspiration requirement. Automatic control of water application at predecided soil water tensions is an effective irrigation scheduling technique. This can be achieved through an indigenously developed auto irrigation system.
In this system soil water tension is sensed through a modified manometer type tensiometer. The design provides control of irrigation at the predecided soil water tensions and preprogrammed timer. The circuitry can be operated with a 12 V d.c. storage battery for a long period.
