1.1 Problem Summary (What exact problems are you trying to solve?) and

Introduction

In India „Agriculture‟ has its own history. If we check the statistics of world‟s

country we can say that India ranks second in farm output. 13.7% of the GDP (Gross

Domestic Product) was accounted for agriculture and allied sectors in 2013; about 50% of

the workforce depends on farming. The contribution of agriculture to India‟s GDP is

steadily decreasing with the countries less attention over farmers. Still agriculture is the

broadest sector and plays a significant role in the overall social fabric of India.

Today automobile industries, mills and factories are expanding their areas in

India. One side these are beneficial for us as it provides job and products and at the other

side these are polluting our environment. And have become a serious challenge for global

warming. Global warming is affecting our climate and we face uncertain change in our

environment which damages our agricultural crop. As told in above passage, In India

about 50% of people depends on agriculture. And global warming is one of the major

problems for them. Recently India faced a big drought in Vidarbha area of Maharashtra.

The announced by government after one year was gone. Some of the farmers were

suffered too much by this drought even some did suicide.

Some of the crops of specific season are not able to get required climatic

conditions due to uncertain change in our environment due to greenhouse effect. Some of

the Industries are polluting rivers by ejecting harmful chemicals in it. Some horticultural

plants don‟t grow due to insufficient watering and some due to insufficient temperature

and etc. Green house is one and only solution against uncertain climate change or global

warming. Green house helps our farmers to create an artificial environment for

maintaining required temperature, humidity and light. Today Green house systems are

available in market as user desires it to work like. But the problem is user has to observe

it continuously to check whether it is working properly or not. There is no effective

monitoring of green house systems to monitor the green house climate conditions at

unbounded distance.


Green house systems need proper care. For example, we have to fill water

manually or make water pump on at ourselves. Means systems are less automatic. They

cannot be monitored from Rajkot at Ahmedabad. Or the installation of green house

systems available in market is quite complex means customer cannot operate it as he

wants.

Here we are designing a green house system fully automatic and monitoring of it

can be done from anywhere in the world having net access. In our system we have used

three main sensors needed to check climatic changes in our environment. The sensors we

have used are light sensor, humidity sensor and temperature sensor. A microcontroller is

used to operate on these sensors and to provide required light, water and heat when the

environment has some change. Internet of things is interfaced through a computer system.

Internet of things make monitoring of system accessible everywhere having net access on

any device.


1.2 Aim and objectives of the project

A greenhouse is an important part of the agriculture and horticulture sectors in our

country. It is used for growing plants faster at any season whether the climate is according

to plant or not. Automatic monitoring and controlling of the climatic parameters will

directly or indirectly govern the plant growth and hence their production. Green houses

are used where climatic conditions are not as expected. At those places Green houses are

used as an artificial environment to create required environmental conditions.

Main aim of this project is to help farmers even in opposite environmental

conditions like in overheat and less humidity conditions. Here controlling part will be

handled by our microcontroller and monitoring part will be handled by the computer and

the data will be sent to cloud through website created. So user will not need to go to their

sight and observe the conditions. Through web interface our user will have comfort to

monitor their system from their home or any place. No need to have specific application

or Bluetooth devices to monitor the conditions.


1.3 Problem Specifications

Prior green house systems were not using microcontroller. Means the systems were

not automatic. User checks the conditions and takes proper action.

After sometime the green house systems were made automatic means system will

work for the user and takes proper action to maintain climatic conditions. But

monitoring was done by live presence of user.

After some time monitoring was made easy and user was able to monitor the green

house from his home. Here the distance from the system was limited.

Manufacturers use Bluetooth app or system specific screen having data of green house

climatic conditions. Here also the monitoring becomes bounded.

2.5 IMPLEMENTATION STRATEGY

1. AEIOU SUMMARY CANVAS:

We have done some activity like we visited a village of farmers, went to farms

having green house system implemented. And watched the techniques how mass

production is being done.

We visited farms, bungalows, green areas, industries and zoo for checking the

environment maintained in green house.

We interacted with our friends, vendors, businessmen, farmers and searched on

Google.

Common objects we observed in green house were different types of sensors,

controlling machine and monitoring screen.

Green house systems are being used by farmers, individuals, food experts,

industries and smart farms.

2. IDEATION CANVAS:

Farmers, individuals, food experts, industries and smart farms are using

conventional green house system implementations.

They are using machine manually and not taking any automatic work.

In situations watering is slow; user has to himself on the water pump.

Possible solutions are designing a machine with automatic work and an effective

monitoring platform.

3. PRODUCT DEVELOPMENT CANVAS:

Purpose of designing this system is to automate the controlling part and make the

monitoring worldwide.

This system will be helpful to farmers, individuals, food experts, industries and

smart farms.

AT89S52 microcontroller is central controlling processor. LDR, LM35 are

sensors which will sense the light and temperature and through ADC outputs of

sensors will be converted to digital form and will be given to microcontroller then

microcontroller will on the light, cooling fan or bulb if needed.


4. EMPATHY SUMMARY CANVAS:

To fulfill this canvas we interacted with different users using green house systems.

They told us their problems related to existing green house systems and we listed

those problems.

We searched on internet about those problems like system was not working

automatically and monitoring was possible up to some distance.

Heater sometimes goes overheated

By manually operating green house systems farmers were happy when they were

near to the system.

3.2 Micro controller AT89S52:

8051 is the name of a big family of microcontrollers. The device which we used in

our project was the 'AT89S52' which is a typical 8051 microcontroller manufactured by

Atmel™. The block diagram provided by Atmel™ in their datasheet that showed the

architecture of 89S52 device seemed a bit complicated. A simpler architecture can be

represented below

The 89S52 has 4 different ports, each one having 8 Input/output lines providing a total of

32 I/O lines. Those ports can be used to output DATA and orders do other devices, or to

read the state of a sensor, or a switch. Most of the ports of the 89S52 have 'dual function'

meaning that they can be used for two different functions.

The first one is to perform input/output operations and the second one is used to

implement special features of the microcontroller like counting external pulses,

interrupting the execution of the program according to external events, performing serial

data transfer or connecting the chip to a computer to update the software. Each port has 8


pins, and will be treated from the software point of view as an 8-bit variable called

'register', each bit being connected to a different Input/output pin.

There are two different memory types: RAM and EEPROM. Shortly, RAM is used to

store variable during program execution, while the EEPROM memory is used to store the

program itself, that's why it is often referred to as the 'program memory'. It is clear that

the CPU (Central Processing Unit) is the heart of the micro controllers. It is the CPU that

will Read the program from the FLASH memory and execute it by interacting with the

different peripherals.

Diagram below shows the pin configuration of the 89S52, where the function of each pin

is written next to it, and, if it exists, the dual function is written between brackets. Note

that the pins that have dual functions can still be used normally as an input/output pin.

Unless the program uses their dual functions, all the 32 I/O pins of the microcontroller are

configured as input/output pins.


3.3 ADC 0804

Analog to digital converters find huge application as an intermediate device to

convert the signals from analog to digital form. These digital signals are used for further

processing by the digital processors. Various sensors like temperature, pressure, force etc.

convert the physical characteristics into electrical signals that are analog in nature.

ADC0804 is a very commonly used 8-bit analog to digital convertor. It is a single

channel IC, i.e., it can take only one analog signal as input. The digital outputs vary from

0 to a maximum of 255. The step size can be adjusted by setting the reference voltage at

pin9. When this pin is not connected, the default reference voltage is the operating

voltage, i.e., Vcc. The step size at 5V is 19.53mV (5V/255), i.e., for every 19.53mV rise

in the analog input, the output varies by 1 unit. To set a particular voltage level as the

reference value, this pin is connected to half the voltage. For example, to set a reference

of 4V (Vref), pin9 is connected to 2V (Vref/2), thereby reducing the step size to 15.62mV

(4V/255).

ADC0804 needs a clock to operate. The time taken to convert the analog value to

digital value is dependent on this clock source. An external clock can be given at the

Clock IN pin. ADC 0804 also has an inbuilt clock which can be used in absence of

external clock. A suitable RC circuit is connected between the Clock IN and Clock R pins

to use the internal clock.


3.4 Light Dependent Resistor (LDR)

A Light Dependent Resistor (LDR) or a photo resistor is a device whose

resistivity is a function of the incident electromagnetic radiation. Hence, they are light

sensitive devices.

They are also called as photo conductors, photo conductive cells or simply

photocells. They are made up of semiconductor materials having high resistance. There

are many different symbols used to indicate a LDR, one of the most commonly used

symbol is shown in the figure below. The arrow indicates light falling on it.

A light dependent resistor works on the principle of photo-conductivity. Photo

conductivity is an optical phenomenon in which the materials conductivity is increased

when light is absorbed by the material.

When light falls i.e. when the photons fall on the device, the electrons in the

valence band of the semiconductor material are excited to the conduction band. These

photons in the incident light should have energy greater than the band gap of the

semiconductor material to make the electrons jump from the valence band to the

conduction band. Hence when light having enough energy strikes on the device, more and

more electrons are excited to the conduction band which results in large number of charge

carriers. The result of this process is more and more current starts flowing throgh the

device when the circuit is closed and hence it is said that the resistance of the device has

been decreased. This is the most common working principle of LDR.


LDR‟s are light dependent devices whose resistance is decreased when light falls

on them and that is increased in the dark. When a light dependent resistor is kept in dark,

its resistance is very high. This resistance is called as dark resistance. It can be as high as

1012 Ω and if the device is allowed to absorb light its resistance will be decreased

drastically. If a constant voltage is applied to it and intensity of light is increased the

current starts increasing. Figure below shows resistance vs. illumination curve for a

particular LDR.


3.5 LM35 Temperature Sensor

The LM35 series are precision integrated-circuit temperature sensors, whose

output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35

thus has an advantage over linear temperature sensors calibrated in ° Kelvin, as the user is

not required to subtract a large constant voltage from its output to obtain convenient

Centigrade scaling. The LM35 does not require any external calibration or trimming to

provide typical accuracies of ±1⁄4°C at room temperature and ±3⁄4°C over a full −55 to

+150°C temperature range. Low cost is assured by trimming and calibration at the wafer

level. The LM35‟s low output impedance, linear output, and precise inherent calibration

make interfacing to readout or control circuitry especially easy. It can be used with single

power supplies, or with plus and minus supplies. As it draws only 60 μA from its supply,

it has very low self-heating, less than 0.1°C in still air.


3.6 Humidity Sensor

A capacitive humidity sensor detects humidity based on a change of capacitance

between two detection electrodes on a semiconductor substrate.

A resistive humidity sensor detects humidity by measuring the change in the

resistance of a humidity-sensitive resistor (humistor).

An impedance humidity sensor changes its electrical impedance as the humidity

of the surrounding environment changes.

A mechanical humidity sensor activates a switch in response to humidity, driven

by the difference in expansion between one humidity-sensitive fiber and one

humidity-insensitive fiber.


3.7 MAX 232

Description:

Max232 is designed by Maxim Integrated Products. This IC is widely used in

RS232 Communication systems in which the conversion of voltage level is required to

make TTL devices to be compatible with PC serial port and vice versa. This chip contains

charge pumps which pumps the voltage to the Desired Level. It can be powered by a

single +5 volt power supply and its output can reach +_7.5 volts.MAX232 comes in 16

Pin Dip and many other packages and it contains Dual Drivers. It can be used as a

hardware layer convertor for 2 systems to communicate simultaneously.Max232 is one of

the versatile IC to use in most of the signal voltage level conversion problems.

3.8 System working:

For power supply in the “Greenhouse Monitoring and Control System” to provide 5V and

12V, the circuit consists of step down transformer of 230/12V. This transformer steps

down 230V AC from main supply to 12V AC. Then that 12V AC is converted into 12V

DC with the help of bridge rectifier. After that a 1000/25V capacitor is used to filter the

ripples and then it passes through voltage regulator. There are two power supply arranged

in same manner one containing 500mA transformer and second has 750mA transformer.

This project comprises of sensors, Analog to Digital Converter (ADC), Micro – controller

AT89S52, Relay driver IC (ULN2003), Relays, MAX 232 IC, dB9 connector and laptop.

The AT89S52 micro – controller is as the heart of the system, it makes the set-up low-

cost and effective nevertheless. Each sensor gives their measured parameter found to the

micro – controller through ADC after being converted to a digital form. When any one of

the parameter read by the controller crosses a safety limitation which has to be maintained

for protection of the crops, then micro-controller performs the required actions by

employing relays until the strayed-out parameter has been brought back to its optimum

level.

Monitoring of parameters is done through IOT means internet of things. We have taken

outputs from micro-controller through MAX 232 IC and laptop takes the reading of

different sensors and checks the green house condition and sends the data on server

created by us which is then accessed by user at any place.

For example when temperature exceeds its level microcontroller will on the cooling fan

connected with relay. Same way when temperature is lower, microcontroller will on the

bulb or heater. Hence the temperature will be maintained.

daily lives and what information is stored about us. This cloud computing is free to use

anytime and anywhere as long as the computer is connected with the Internet. This

monitoring system percepts different parameters inside the greenhouse using sensors,

GSM, and cloud to provide the updates. The developed system can be proved profitable
