INTRODUCTION

What is Greenhouse?
A greenhouse is an outlined
homestead structure building to
give a more controllable
environment to better harvest
generation, crop security, product
seeding and Transplanting.
OBJECTIVE


Build miniature greenhouse which is equipped with automatic 
monitoring and controlling system

Constantly monitor and control environmental conditions in 
Greenhouse to ensure it reamins at present temperature, moisture and 
humidity levels

It focuses on saving water,increasing efficiency and reducing the 
environmetal impacts on plants production

The user can see the atmosperic condition of the greenhose plants on 
website and control the greenhouse from far away places
Existing system

Existing system:

The existing system has the ability to yet lack tha ability to control
indoor humidity.Greenhouse monitoring and controlling is a complete
system designed to monitor and control the humidity inside a
greenhouse.The software uses an Android mobile phone,connected
using Wi-Fi to a central server which connects via serial
communication to a microcontroller and humidity sensor.
Proposed System

Proposed System:

smart greenhouse monitoring and controlling system is used to monitor and control
the humidity,temperature and soil moisture levels to achieve the maximum plants
growth.The hardware system contains Atmega328 microntroller as the main
processing unit and it gets input from the temperature,humidity and soil moisture
sensors.

Based on the data obtained from the sensors,the microntrollers control tha actuator
components such as cooling fan,LED,water pump,to achieve the system
requirements.

It also uses OLED display to display data obtained fromthe sensors..

ARDUINO UNO BOARD

The Arduino UNO ATmega328 Microcontroller Development Board is based
on the ATmega328 development board.


Arduino UNO which is a 5V 16MHz board. The board includes a USB
interface port, a reset button, digital I/O (input/output)and an ICSP.
OLED DISPLAY

OLED stand for organic light         
 emitting diode

 128x64 OLED Display has the 
outlinedimension of 26.70 x 19.26 
mm 

OLEDalso known as an organicEL 
(organic electroluminescent) diode

It  is a light­emitting diode (LED) 
in which the emissive 
electroluminescent layer is a film 
of organic compound that emits 
light in response to an electric 
current.
MOTOR DRIVER


The L298N is a dual H­Bridge motor    
driver which allows speed and           
direction control of  two DC motors at 
the same time.

 The module can drive DC motors 
that have voltages between 5 and 35V, 
with a peak   current up to 2A.

This depends on the voltage used at 
the motors VCC.
TEMPERATURE AND HUMIDITY SENSOR


The DHT22 is a basic, low­cost           
 digital temperature and humidity        
  sensor. 

It uses a capacitive humidity               
 sensor and a thermistor to measure    
the surrounding air, and spits out a      
digital signal on the data pin (no          
analog input pins needed).

Its temperature measuring range is     
from ­40 to +125 degrees Celsius 

Also the DHT22 sensor has better       
 humidity measuring range, from 0 to  
  100%
SOIL MOISTURE SENSOR

Soil

moisture sensors measure
the volumetric water content in
soil.

The probe can be powered with
an DC supply or batteries in the
range of 3.5 to 20 volts.
ACTUATORS

ARDUINO IDE
The arduino  IDE (Integrated Development Environment) is 
basically a software that enables better and assisted code 
editing, compiling and debugging, then burning the code into 
the arduino development board. The Arduino IDE runs on the 
Java Platform.
 ADVANTAGES

Automatically control environmental conditions within greenhouse allowing 

any type of plant to be grown all year round


Eliminates risk of greenhouse not being maintained at specific conditions due to 
human error


Minimizes labor costs involved in maintaining a greenhouse



APPLICATIONS

It can be used in Greenhouses to control the temperature,soil
moisture and humidity for the proper growth of plants

With little modifications ,this project can be used in mechanical
companies to measure various parameters of operating machines
like temperature and light

Temperature monitoring and controlling action can be used in
home or various halls like conference room,seminor hall to control
the temperature of room
FUTURE SCOPE

Greenhouse technology has tremendous scope in horicultural
sector,especially for production of hybrid seeds,high value
vegetabels,medicinal plants,flowers and fruits which fetch more prices
in domestic as well as international markets


This will make for a good climate control system .Fourther more,most
plants have one temperature during the day and a different one at
night time.This would make it possible to change the preffered
temperature range during the course of the day.
CONCLUSION


Temperature ,humidity and moisture sensors are used in this
project which gives the exact value of temperature,moisture
respectively.These sensors give the correct result according to
the plant condition

Controlling environmental condition of the greenhouse
which reduces the cost, increases the efficiency of crop field
and proposing an Android application for remotely accessing
the greenhouse environment which will reduce the human
effort.
