2. Introduction
 Irrigation is an artificial supplying of water to the root of
plants.
 The old methods which is use for irrigation are – watering
cans , water channels that have to open or close
manually.
 In this case a lot of water is wasted in this process.
 An automated irrigation system needs to develop to
optimize water use for agricultural crops.
 An intelligent irrigation system has to have all the
components that autonomously monitors or control the
level of water available to the plant without any failure.

3. CONTENT
 Introduction
 METHODOLOGY
 IRRIGATION CONTROL
 PESTICIDE CONTROL
 MICRO-CONTROLLER
 SOIL MOISTURE SENSOR
 Solenoid-valve

4. METHODOLOGY
 Irrigation using soil moisture sensors and Microcontroller.
 automatically feed plants with water according to their
need without farmer’s interference.
 sprinkle the pesticide mixture uniformly in the desired
ratio deserved by the plants automatically
 Soil moisture sensors help to know the status of the water
level in the farm.
 Solenoid valves for controlling water flow to the farm.

5. IRRIGATION CONTROL SYSTEM
 Use for watering the plant
in field.
 When all the fields
acquire sufficient water
levels, then the system is
programmed to shut off
the main motor.

6. PESTICIDE CONTROL
 this mechanism use for mix and
spray the fertilizers to the plants
in a definite proportion.
 two motors are needed in order
to pump the water and
pesticides to a tank where it can
be mixed thoroughly .

7. MICRO-CONTROLLER
 Microcontroller ATMEL
89S52 is the heart of the
system.
 It is a single chip
Microcomputer with I/O
ports.
 It can be used for many
control applications like
motor speed control,
waveform generation etc.

8. SOIL MOISTURE SENSOR
 Soil moisture sensors
measure the water
content in soil.
 A soil moisture probe is
made up of multiple soil
moisture sensors.
 designed to estimate soil
volumetric water content
based on the dielectric
constant of the soil.

9. Solenoid-Valve
 It is an electromechanical valve for use with liquid
or gas.
 A solenoid is an electromechanical device which
allows for an electrical device to control the flow
of a gas or liquid.
 The valve then changes state, either opening or
closing to allow a liquid or gas to either flow
through or be blocked by the solenoid valve.
 This is applicable in controlling the hydraulic
actions.

10. LM324 Comparator
 It is integrated circuit use as a
motor driver.
 Advantages of LM324 Comparator
are :
 The LM324 is used as both like
comparator and op-amp
 LM324 is a high-gain electronic
voltage amplifier

11. Advantages
 Highly sensitive
 Work according to the soil condition
 Fit and forget system
 Low cost and reliable circuit
 Complete elimination of manpower
 System can be switched into manual mode whenever
required.

12. Disadvantages
 There are cost in purchasing , installing and maintaining
automatic equipment.
 Sometimes failure will occur.

13. Conclusion
 Automatic irrigation control system has been design and
constructed.
 The system components are readily available , relatively affordable
and operate quite reliably.
 The system help to eliminate the stress of manual irrigation.
 The prototype of system worked according to specifications.
