ABSTRACT
The growing needs of man and the increasing population of earth causes the scarcity
of water. This greatly aects the plants, and the requirement water management is high.
Water use has been growing globally at more than twice the rate of population increases in
the last century, and an increasing number of regions are reaching the limit at which water
services can be sustainably delivered, especially in arid regions. In the present scenario the
conventional methods of watering, like ood mode and sprinkler, is not that much eective
and is responsible for water wastage. Improper watering systems create breeding areas for
disease spreading organisms. Hence, the way watering pants must be smart, and this is
achieved by watering plants depending on the necessity of plants and the moisture level of
water. This project deals with an automated plant watering system that senses the moisture
content of the soil thus determining the necessity of pumping water with the collected data.
Also determines the minimum amount of water required to maintain the balance between
the soil defensible water and environment parameters.
KEYWORDS
Arduino, Soil moisture sensor, Power supply, Relay.

1. INTRODUCTION
At the present scenario, in the era of innovation where the technology is growing in terms
of electrical and other new technologies, the life of people must be uncomplicated and more
favorable and there is a need for lot of self-working system that are able to replace or bring
down man's eort in their daily tasks. We propose a similar system called automatic self-plant
watering system, which is basically a framework of monitoring planting and agriculture
opportunities that uses sensors to detect the soil moisture content with a microcontroller
and Arduino .Since asymmetrical watering results in plant ecient elements loss in the
soil and may even results in spoil of the plants, Finding the method to nd weather the
watering is necessary or not and to give what we have to water the plants is foremost. Due to
social process and inadequacy of place people started growing plants in an unt windowsill
location. It is very essential to use the water assets and a system is mandatory, to manage this
task without man's existence. Machine-controlled watering system estimates and processes
the existing plant and then materials required along with the amount of water quantity
needed by that plant, dropping the amount of water to let the plants be water ecient.
2. MATERIALS AND METHOD
Materials:
Arduino, soil moisture sensor, power supply, relay, water motor.
Method:
The method of owing water all by itself and monitoring the same in a display to let the
user know about it is the second major task we need to solve. When the Arduino gets level 1
as input the user gets a display word of it and the rst level of watering is done to maintain
the water moisture level required to match the water. It has a system that can deliver a
heavy load to pump the water. The opposite work happens when the logic-low is received.
We use a moisture detector that uses a sensing element in it to nd the amount of moisture
present in the soil and is connected to an external micro controller like an AVR or Arduino.
The Arduino is connected to a computer to load a program to save the obtained results and

give the output to a display and to control the amount of water ow. Also, we use a moisture
sensor to nd the amount of watering required for further ow of plant to be healthy.
3. RESULTS
The result of the project declares that, if the soil moisture is low then moisture sensor sends
signal as level 1 to Arduino and it passes signal to relay which switches the power to the
motor pump and provides water to the plant. If soil moisture is high, then the sensor send
signal as level 0 and Arduino will not pass any signal to relay.

4. CONCLUSIONS
The proposed system provides a vague output and cannot be dependent completely as
all the plants are not having the same requirements for its watering needs. Some plants
can be survived with less amount of water and withstand drought conditions. Monitoring
a watering system based on the soil moisture level is not much ecient but provides a
temporary solution to solve the problem. The development of the project must be further

done depending on the amount of water required for the specic plant. Automatic irrigation
systems improve water use and Reduce water wastage. This project can Contribute to socio-
economic development. It has a quick response and is computer user friendly. The primary
use of this program is farmers and Gardeners do not have enough time for their watering,
they do not miss crops or plants. This project is also an application for farmers wasting
water unknowingly during irrigation. The main purpose of this smart project is, it is very
innovative, user friendly, less time consuming, and more ecient than the existing system.
