5. 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. 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.
8. Solar panels :
Solar panels are those devices which are used to absorb the
sun's rays and
convert them into electricity or heat.

11. Battery & Relay
To store solar energy a 12V sealed lead acid rechargeable battery is used
Battery backup time is calculated as:
Back up time = Battery Power in Watt
hour (Wh)/Connected Load in Watts (W)
Battery Power in Wh = Battery Capacity in
AH x
Battery Voltage (V) x Number of Batteries

A relay is an electromagnetic switch that is
used to turn on and turn off a circuit by a low
power signal, or where several circuits must
be controlled by one signal. We are used 220v
-AC 10A relay in this project.
We are used two relay in this project , one is
decide which through of the pump input and
other relay working when the pump is off or
off

12. Moisture sensor & Pump
This Moisture Sensor can be used to detect
the moisture of soil or judge if there is water
around the sensor, let the plants in your
garden reach out for human help. They can be
very to use, just insert it into the soil and then
read it. If you are a gardener, you can use this
sensor to know when your plants need to be
watered.
We are used 5v dc submersible
pump in this project .This water
pump can be submersible, which it is
convenient and useful.

13. Facilities:
Low man power cost
Environment friendly
Save energy and Maintenance cost low
More efficient than the manual system
Disadvantage:
Installation cost high
Facilities & Disadvantage
14. 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.
