it is a prototype arduino based auto irrigation system which turns on the pump while the field is dry. it uses soil moisture sensor to detect the amount of soil moisture content. As the system is arduino based it uses an arduino software which can be downloaded from https://www.arduino.cc/en/Main/Software
The project is designed to develop an automatic irrigation system which switches the pump motor ON/OFF on sensing the moisture content of the soil. In the field of agriculture, use of proper method of irrigation is important. The advantage of using this method is to reduce human intervention and still ensure proper irrigation.
The project uses an arduino which is programmed to receive the input signal of varying moisture condition of the soil through the sensing arrangement. This is achieved by using an arduino which acts as interface between the sensing arrangement . Once the controller receives this signal, it generates an output that drives a relay for operating the water pump. An LCD display is also interfaced to the microcontroller to display status of the soil and water pump. The sensing arrangement is made by using two stiff metallic rods inserted into the field at a distance. Connections from the metallic rods are interfaced to the control unit.
The concept in future can be enhanced by integrating GSM technology, such that whenever the water pump switches ON/OFF, an SMS is delivered to the concerned person regarding the status of the pump. We can also control the pump through SMS.

Modern digitalized era of our 21st century needs automation in each and every sector. Combining technology to increase the credibility of an another technology is not at all a very good idea. India is a country where agriculture is the main and vast field for our national financial system. So we have tried to implement the fruitfulness of technology to combine with agricultural field so that the growth of crops can increase exponentially. Irrigation is the methodology of misleadingly supplying water to land where harvests are developed. Generally hand pumps, channel water and precipitation were a significant wellspring of water supply for watering system. This strategy has prompted serious disadvantages like under watering system, over-watering system which thus causes filtering and loss of supplement substance of soil. Changing ecological conditions and lack of water have prompted the requirement for a framework which effectively oversees watering system of fields. Computerized watering system framework is a machine based framework, which robotizes the watering system of area by joining different programming and equipment approaches together for field watering system.
This paper manages a definite study of different GSM based mechanized ranch watering system frameworks. GSM serves as an essential part since it is in charge of controlling the watering system office and sends them to recipient through coded sign. Our study is focused on examination of different GSM approach.
Automated irrigation system based on soil moisture using arduino boardjournalBEEI
In recent years, the best system of irrigation is studied by reducing the wasted amount of water and electricity. Automatic irrigation is the use of a device to operate irrigation structures so the change of flow of water from one bay, or set of bays, to another can occur in the absence of the irrigator. In this work, automatic control system of solar irrigation implemented practically using Arduino board. This photovoltaic (PV) system is applied in the garden of Engineering Technical College- Mosul (city in Iraq). PV system can be adjusted by many regions in Iraq where it planned to connect on small part of land. Irrigation process is controlled depending on moisture sensor that connected to sense the soil moisture and giving data to Arduino read pin. According to the program that uploaded to Arduino, DC pump can be controlled as ON-state or OFF-state as respect to the soil moisture percentage ratio. Finally, the practical results are approximately similar to that obtained from proteus Arduino simulator.

The aim of our project is to minimize this manual intervention by the farmer. Automated Irrigation system will serve the following purposes: 1) As there is no un-planned usage of water, a lot of water is saved from being wasted. 2) The irrigation is the only when there is not enough moisture in the soil and the sensors decides when should the pump be turned on/off, saves a lot time for the farmers. This also gives much needed rest to the farmers, as they don’t have to go and turn the pump on/off manually.
"Automatic Intelligent Plant Irrigation System using Arduino and GSM board"Disha Modi
Automatic irrigation is a form of irrigation system that incorporates the theory of control, power of wireless technology and feedback system with irrigation. The aim of our project is not only to minimize this manual intervention by the farmer in farm field, but also to successfully water garden plants planted in pots too. Which is why we are using micro- controller based Automated Irrigation system will serve the following purposes: 1) As there is no un-planned usage of water, a lot of water is saved from being wasted. 2) The irrigation is done only when there is not enough moisture in the soil and the microcontroller decides when should the pump be turned on/off, saves a lot time for the farmers. This also gives much needed rest to the farmers and helps, as they don’t have to go and turn the pump on/off manually. 3)This irrigation system can be monitor by user wirelessly. User can receive notification and can provide proper commands via his cell phone whenever necessary.
Irrigation is one of the fundamental evils in agriculture in developing countries. Usually
the farmers don’t have much awareness on how to irrigate effectively, so they tend to use more water
than required for agriculture by manually. Automatic irrigation system is developed to optimize
water use for agricultural crops in which the humidity sensor, temperature sensor, float sensor, flow
sensor are placed on the root zone of the plants. This project is designed to overcome these problems.
The algorithm which is developed with set values of these sensor and it can be programmed into PIC
microcontroller to control the water flowing. With the help of embedded technology it is easy to
control the environmental conditions such as soil moisture, temperature, float and flow level. These
components are powered by rechargeable batteries and these are charged by photovoltaic panel to
achieve full energy. This technique allows the farmers to gather the information about the soil
conditions through Zig-bee technology .This project offers an optimal solution to support irrigation
management that allows farmers to increase their productivity with minimum usage of water.
This paper presents the design and the implementation of a new microcontroller-based solar
Power inverter. The aim of this paper is to design single phase inverter which can convert DC voltage
to AC voltage at high efficiency and low cost. Solar and wind powered electricity generation are
being favored nowadays as the world increasingly focuses on environmental concerns. Power
inverters, which convert solar-cell DC into domestic-use AC, are one of the key technologies for
delivering efficient AC power The hardware and software design are oriented towards a single-chip
microcontroller-based system, hence minimizing the size and cost. With this new approach the
modularization of the conversion from solar power to electric power at its maximum power point can
be made more compact and more reliable.

AUTOMATED LIGHT CONTROL SYSTEM FOR OFFICESDrm Kapoor
Electricity is one of the most important resources in this century that should be conserved. On several occasions, we get out of rooms, offices, hall and forget to turn off the lights/fan, thus the electricity is wasted and billing is also increased. Manual operation of light in offices is one of the challenges being faced by members of staff in any organization. This research work is focused on design and implementation of an automatic light controller used in offices in order conserve electricity as well as reducing electricity bill.. The major component used for the implementation of this research was Light Dependent Resistor (LDR) which works on the principle of changes in resistance of LDR according to light falling on it. This will ensure proper conservation of energy which reduces the cost of bill paying to IBDEC (Ibadan District Electricity Company). Manual application of controlling bulbs is eliminated by using this system. This automated system is not only applicable to offices but also applicable in, rooms, Hostels, Street lights, Garden lights, Hotels etc. Automatic light control requires less labor to operate since it works automatically therefore the running and opportunity cost is encouraging.

There is a requirement to design a system to sense the presence of glass bottles leaving an
automatic washer on a production line conveyor belt. The production line is for food products
and the environment is clean and maintained at a temperature of 15 degree C. The system must
meet the following criteria: The switching distance will lie between 5 and 20 mm. The output
from the sensor is to be of binary form, i.e. logical 1 when the part is present and logical 0 when
no part is present. It is necessary to ensure that a change of sensor state occurs closer to the
sensor when a bottle approaches than when it moves away. Bottles will pass the sensor at the
rate of 10 every second. There is no requirement for protection from contact with objects but it
must be proof against water drips. Recommend a suitable sensor and justify your

2. opposes any change of voltage in the circuit in which it is connected;
3. Blocks the passage of direct current through it.
CAPACITOR
The electronic component (mostly a coil) which opposes the change of current in circuit is
called an inductor. The ability of coil or inductor due to which it opposes the change of current

Sensors
IR Sensors work by using a specific light sensor to detect a select light wavelength in the Infra-
Red (IR) spectrum. By using an LED which produces light at the same wavelength as what the
sensor is looking for, you can look at the intensity of the received light. When an object is close
to the sensor, the light from the LED bounces off the object and into the light sensor. This results
in a large jump in the intensity, which can be detected using a threshold

3. ABSTRACT
Irrigation is the key to a successful garden. Long
gone are the days of manual watering or relying on a
friend to water when you are on vacation or away on
business.
The Project presented here waters your plants
regularly when you are out for vocation. The circuit
comprises sensor parts built using op-amp IC

4. Two stiff copper wires are inserted in the soil to
sense the whether the Soil is wet or dry.
The comparator monitors the sensors and when
sensors sense the dry condition then the project will
switch on the motor and it will switch off the motor
when the sensors are in wet. The comparator does
the above job it receives the signals from the sensors.
7. The solar cell is composed of the semiconductors of
the P-N junctions.
It can convert light into electric energy. Therefore we
can assume that electricity produced using sunlight
shining on the solar cell can be used like common
electricity.

7805 three terminal voltage regulator is used for voltage
regulation.
Bridge type full wave rectifier is used to rectify the ac out
put of secondary of 230/12V step down transformer.
10. LM324
The LM324 series consists of four independent, high gain,
internally frequency compensated operational amplifiers which
were designed specifically to operate from a single power
supply over a wide range of voltages
Features
Internally frequency compensated for unity gain
Large DC voltage gain 100 dB
Wide bandwidth (unity gain) 1 MHz (temperature
compensated)
Wide power supply range: Single supply 3V to 32V or dual
supplies ±1.5V to ±16V
Very low supply current drain (700 μA)—essentially
independent of supply voltage

12. RELAYS
A relay is an electrically controllable switch widely used in
industrial controls, automobiles and appliances.
13. AC MOTOR
An electric motor uses electrical energy to produce
mechanical energy

such as fans, refrigerators, washing machines, pool
pumps, floor vacuums, and fan-forced ovens.
14. ADVANTAGES
Highly sensitive
Works according to the soil condition
Fit and Forget system
Low cost and reliable circuit
Complete elimination of manpower
Can handle heavy loads up to 7A
System can be switched into manual mode whenever
required
16. WORKING PROCEDURE:
Switch ON the power supply. Each and every module
require +5vdc of supply. In this project, we will be using
two metal plates and we will be inserting it into the soil
and sets some reference voltage. When ever the soil dry-
wet sensor voltage is less than the reference voltage then
that signals goes to LM324 Comparator.
This comparator switches ON the water pump through
Relay automatically when the soil is DRY. To drive the
relay we are using transistor driver because relay requires
high current of 10 to 20 mile amps.
And when the soil dry-wet sensor voltage is higher than
the reference voltage then that signals goes to LM324
Comparator.
This comparator switches OFF the water pump through
Relay automatically when the soil is WET.
So, in this way we are reducing the man power.
17. The project “Intelligent Automatic Plant
Irrigation System ” is designed, tested
and implemented successfully. It is
much easy and cost effective.
