3. Abstract :
• This paper proposes a model of variable rate
automatic micro controller based irrigation
system. Solar power is used as only the source
of the power to control the overall system.
Sensors are placed on the paddy field and these
sensors continuously sense the water level and
give the message to the paddy fields, farmers
can get the information about the water level, a
farmer can control the motor by sending a
message from his cellular phone even from a
remote place. However, if the water level
reached the danger level, the motor will
automatically start without confirmation of farmer
to ensure the proper waste level in the site.

4. o In this paper we propose an automatic
irrigation system using solar power which
drives water pumps to pump water from
bore well to a tank and the outlet valve of
tank is automatically regulated using
controller and moisture sensor to control
the flow rate of water from the tank to the
irrigation field which optimizes the use of
the water.

9. Advantages :
It saves time.
Save water while keeping a lush lawn.
Achieve a thriving yard while saving
money
Efficient
Automation
Cost effective

10. Conclusion:
This model is designed and implemented
considering low cost, reliability, alternate
source of power and automatic control.
It always ensures the sufficient level of
water in the paddy field avoiding the under-
irrigation and over-irrigation.
Farmers can remotely ON/OFF the motor
by using cell phone even from away.
The system is secured with password for
the restricted number of users.
