OBJECTIVE:• To tackle the problems of agricultural sector regarding irrigation
system with available water resources.
• New concepts are being developed to allow agricultural
automation to flourish and deliver its full potential, so we
consider the implication of developing a new single technology
of Automatic plant irrigation system using AT89S52 MCU
An embedded system is a special purpose
computer system designed to perform one or a few
dedicated functions, often with real time
computing constraints.
It is usually embedded as part of a complete
device including hardware and mechanical parts.
BLOCK DIAGRAM:
POWER SUPPLY UNIT:
AT89S52 Microcontroller:
• The AT89S52 is a low-power, high-performance CMOS 8-bit
microcontroller with 8K bytes of in-system programmable flash
memory.
• By combining a versatile 8-bit CPU with in-system
programmable flash on a monolithic chip, the Atmel AT89S52
is a powerful microcontroller which provides a highly-flexible
and cost-effective solution to many embedded control
applications.

inductor
Moisture Sensors:
• It can be also called as a
soil moisture sensor.
• Soil moisture is highly
variable. Accuracy from a
single site isn't enough to
run an experiment.
AC motor:• An electric motor uses
electrical energy to produce
mechanical energy.
• Electric motors are found in
household appliances such
as fans, refrigerators,
washing machines, pool
pumps, floor vacuums, and
fan-forced ovens.
TRAIC (BT136):
TRIAC, from Triode for Alternating
Current, is a generalized trade name for
an electronic component which can
conduct current in either direction when it is
triggered (turned on), and is formally called
bidirectional triode thyristor or bilateral
triode thyristor.
Liquid crystal display (LCD):
• It is a thin, flat panel used for electronically displayinginformation such as text, images, and movingpictures.
• Its uses include monitors for computers, televisions,instrument panels, and other devices ranging fromaircraft cockpit displays, to every-day consumerdevices such as gaming devices, clocks, watches,calculators, and telephones.

•Complete elimination of man power.
•Night-Day mode sensing.
CONCLUSION:• This project presents a high sensitive sensors based
automotive device control.
• The tracking controller based on the closed loop
algorithm is designed and implemented with Atmel
89S52 MCU in embedded system domain.

night – day vision.
FUTURE SCOPE:
• The main scope of this project is to make the
irrigation automated.
• With the use of low cost sensors and the simple
circuitry makes this project a low cost product, which
can be bought by a poor farmer.
• This project is best suited for places where water
is scares and to be used in limited quantity.
