This document describes a GSM based automatic irrigation system. The system uses soil moisture sensors to detect the moisture level in soil. When the moisture level drops below a threshold, the sensor alerts a microcontroller which sends a signal to a GSM module to call a user's mobile phone. The user can then remotely turn on a water pump by answering the call. When the soil moisture increases, the sensor stops the pump. The system aims to automate irrigation and save water, labor, and time compared to traditional irrigation methods.

3.  OUTLINE
• 60% Of India's land area is agricultural land.
• Irrigation is the artificial application of water to the land or soil.
• It is used to assist in the growing of agricultural crops,
maintenance of landscapes, and re-vegetation of disturbed soils in
dry areas and during periods of inadequate rainfall.

4. • Over Irrigation
• Under Irrigation
• Land is more, we need more
manpower and labor also.
 Problems In Current System

5.  INTRODUCTION
• Based on GSM i.e. system works by using a mobile call
• The system is totally automated
• Easy to operate

7.  WORKING
• Moisture Sensor senses the low moisture content of the
soil.
• Gives a signal to the Microcontroller.
• Microcontroller then gives a signal to the called mobile,
by pressing call receiving button microcontroller get signal
to turn on the valve.
• When the moisture content becomes sufficient, the sensor
senses this and gives back the signal to the Microcontroller.
• Relay gets open and the water pump become turn off.

9.  Soil Moisture Sensor
• Change in moisture is proportional to the
amount of current flowing through the soil.
• For the rice crops DTMF controlled soil
moisture sensor is used.
• Gro-point sensor 37GP-SS
• Gro-point sensor 37GP-HS
• Gro-Point Sensors 37GP-MS
TYPES OF SENSOR:

10.  PIC16F877A Microcontroller
FEATURES:
• 40-44 Pin IC
• High operating speed
• 256byte EEPROM

• It works as a level matcher circuit.

13.  ADVANTAGES
• Saves water
• Improves growth
• Save time
• Adaptable
• Simplest method
• Reduces manpower

14.  APPLICATIONS
• Useful Irrigation in Fields.
• Useful Irrigation In Gardens, Parks.
• This Irrigation System is very efficient for
Paddy, Rice Fields.
• Household purpose.

15.  FUTURE SCOPE
• This system will helps the farmer to overcome the drawbacks of
traditional irrigation system.
• Provide the new technology for farmer to improve the quality of
their irrigation system.
• Also helps to those farmer which do not have sufficient water
for their farming.

16.  CONCLUSION
 The GSM Based Automated Irrigation System will be monitors and controls all the
activities of irrigation system efficiently.
 GSM Based Automated Irrigation System will be a valuable tool for accurate soil moisture
control and it is a simple, precise method of irrigation.
 It will also helps in time saving, removal of human error in adjusting available soil
moisture levels and to maximize their net profits.
