3. Introduction
Agriculture is the backbone of Bangladeshis economy.
It is one of the major occupations for many people in
Bangladesh. Out of 2/3rd water found on the Earth,
only 3.5% is fresh water that can be put into use in any
day-to-day activities. About 55% of this available
freshwater is used in agriculture and 10-30% of this
percentage gets wasted on a regular basis due to many
reasons. Over the years different means of irrigation has
evolved to minimize this wastage of water in
agricultural lands. However, one of the major problems
that still remains, leading to wastage of water, is the
lack of proper knowledge of the farmers about the soil
moisture content, and hence the requirement of the
amount of water in the agricultural soil. [2] Moreover,
due to lack of irrigation the crop to be very low, it's
happen to the load shading. it can be reduced used solar
power system. The global irrigation scenario is
categorized based on increased demand for higher
agricultural productivity and decrease the availability of
water and power.

4. With the advent of open source Arduino boards
along with cheap moisture sensors system, it is
viable to create devices that can monitor the
soil moisture content and accordingly irrigating
and removes the excess water from the fields or
the landscape as an when needed. The proposed
system makes use of microcontroller
ATMEGA328 on Arduino Uno platform and
solar power system which enable farmers to
remotely monitor the status of sprinklers
installed on the farm by knowing the sensor
values thereby, making the farmers.

Methodology
Working Principle :
Main Part:
Soil moisture sensor is used to sense the moisture
content in the soil. The required value of moisture
is fed prior to the microcontroller. Soil moisture
sensor works on the principle of resistance.
When the soil is dry it gives high resistance for
the connection of two electrodes, and when the
moisture content in the soil increases the
resistance given by the soil is less as water being
good conductor of electricity conducts between
the two electrodes.
When the moisture level in the soil is below than
the set value the pump gets on, and when the
moisture content reaches the required level the
power supply to the pump is cut-off.

15. In this thesis we are trying to make a simple renewable energy based
automatic irrigation system which is cost efficient and increase our
irrigation production. Solar water pumping system is reliable and long
lasting. It requires minimum maintenance. Though it is expensive to
install but in the long run it is relatively cost effective. As a developing
country, Bangladesh needs these system so that we can have lower
maintenance cost and can have water for irrigation and other purposes.
With increasing reliance on natural gas and fossil fuels, we run the risk
of exhausting them in the near future. Our region is subject to a healthy
amount of sunshine as the results show, which makes it very important
for us to take initiatives and improve on solar powered technology.
