Our project is based on IOT (Internet of things) which is very useful for monitoring and controlling the greenhouse environment, Agriculture under the greenhouse environment has more benefit of getting more crops by making proper climatic conditions for plants, fruits and vegetables. This greenhouse monitoring environment system have the transparent paper on the top and it contains the five main sensors they are temperature, humidity, rain, soil, LDR sensors. Most of the farmers are fail to get good crops by various reasons such as diseases due to temperature and humidity, if farmers really concerned about suitable temperature and humidity then they can get good crops and this can possible by providing greenhouse environment. The Arduino Nano is the heart of this project, and the five sensors are senses of their respective value and send to the Arduino Nano, through Wi-Fi module the respective detected value is monitored on the smart mobile where Wi-Fi controller app is there. Temperature sensor detects temperature, if temperature exceeds the threshold value then the fan is automatically on, there by temperature are decreases in the greenhouse environment. If LDR detects the sunlight then light will be off and when the sunlight not fall on the LDR then the light will be on in the greenhouse environment. If Rain sensor detects Rain then through the Wi-Fi controller we can open the top of the Greenhouse environment. The top is to be closed after the rain stop, by the Wi-Fi controller. If Soil sensor detects soil is to be dry then automatically the water pump is ON, and water pump is OFF automatically when soil becomes wet.
A conservatory is a expose region where location plants grow and develop. It’s also called dry land of inhibited plants and crops. A glass house ecological authority structure be in debt to the relation of a lot of ecological adaptable influence of extension and construction. The internet of things allows devices to be percepted in passing through live network architecture/configuration to generate opening for either straight absorption of the bodily physical world into computer based system and arising in enriched producing excutness and provident advantage in expansion to be decreased human arbitration. Temperature and LDR sensors are the major essential sensors that employ in this operation whatever gives precise assets of power, temperature, soil, and moisture etc. as individually Keep on observing of such elements required applicable details obtaining to the separate reaction of the numerous components towards acquiring maximum crop presentation These particulars is acquirer from various sensors location and transferred through Wi-Fi module to Wi-Fi controller application in order to fetch all related data on as real screen of this system.

IV. WORKING PRINCIPLE
For the working the Greenhouse will be installed with temperature sensor, light sensor, rain sensor, Soil moisture sensor. To show case that we cover the light sensor, as we can see in the LCD screen and the IOT application display is that the light present is dropped and the light is getting switched ON to overcome the same light condition. When the light sensor senses the light again the bulb is switches OFF automatically.
A. Temperature Sensor
Moving on the temperature sensor which is installed in the greenhouse to show the temperature high, we can see the temperature is increasing as presented on the LCD display and on the Wi-Fi controller app, after a certain temperature with exceeding about the threshold value the fan get automatically switched ON to maintain desired temperature condition. After the temperature condition is normal which is called below the threshold value then fan gets switch OFF automatically.
B. Soil Moisture Sensor
The soil moisture sensor which will be placed in the ground/soil inside the greenhouse to sense the moisture present in the soil, as the moisture in the soil is dropped and it will be sensed by the soil moisture sensor and the pump will get switched ON automatically to restore the moisture condition, that is projected on the LCD screen as well in the Wi-Fi controller app on our smart mobile, as soon as the sensor senses the enough moisture in the soil which makes this condition normal and the pump will get switched OFF automatically.
C. Rain Sensor
The rain sensor which will be placed on the top of the greenhouse to sense the rain, as rain is falls on the rain sensor then on the LCD display as well as in Wi-Fi controller shows the message called “it’s raining” then through the Wi-Fi controller we can give the command called “top open” for opening the top of the greenhouse which is transparent material. After rain stops the LCD and Wi-Fi controller shows the message called “NO rain” then through the Wi-Fi controller we can give the command called “Top closed” for closing the top of the greenhouse.
So, with the help of this project called greenhouse monitoring and controlling through IOT, we can maintain the desired conditions such as climatic conditions for the effective crop growing such as plants, fruits and vegetables. So, this is the working of greenhouse monitoring environment and controlling through IOT platform.
V. HARDWARE DESCRIPTION
A. 16X2 LCD Display
The LCD is familiar as liquid crystal display, it is a mixture of two states, the liquid and solid it fabricates a visible aspect with the help of liquid crystal. The facts and control are two registers for LCD. It carries 16 pins that are .
Temperature is the most commonly measured physical parameter. So clear calculation is wanted many applications such as research lab electrical and electronics components.
Temperature is the degree of coldness/hotness of any device calculated on a distinct scale as Celsius, Fahrenheit etc. This device is an electronic device such magnitude the temperature of its environment and connects the input data into electronic data to record the changes of temperatures.
D. LDR Sensor
Light dependent resistor is also known as photo resistor, LDR is a device whose resistivity is a function of the intenent electromagnetic radiation can light that’s why they are light sensing devices, they are also called as photo conductors. This is made up of semiconducting materials with high resistance. It works on the principle of photo conductivity is an optical phenomenon in which the materials conductivity is reduced. This LDR are less sensitive than other devices.
E. Wi-Fi Module
This module is also known as wireless local area network module. This electronic elements secret in many products to accomplish wireless cellular coupling to internet. This Wi-Fi module is used for the growth of finish point IOT. It is also called as MCU.
F. Arduino Nano
It is a microcontroller board designed by Arduino.cc. The microcontroller which is used in Arduino Nano is ATmega328P, it has 12 digital pins from D2-D13, it is also has 8 analog pins starting from A0-A7. These digital and analog pins are designed by multiple functions. We can interface the various sensors depending upon our requirement to the Arduino Nano. If we interface a motor and LCD it is called output. Arduino Nano can perform 3 types of communication protocols which are:- 1) Serial protocol 2) SPI protocol and 3) 12 protocol. Now pin 0 and 1 are used for serial communication. It also has pwm pins, these pins used for pulse width modulation. It also has two reset pins which are used to reset this Arduino Nano, it also uses crystal oscillator of 16MHz frequency. Arduino Nano has 4 LED’s and are connected to different parameters such as Rx, Tx power supply and the other one is for pin 13 used for testing. Arduino Nano has three types of building memory associated with it, those memories are named as 1)Flash memory 2)SRAM memory and 3)EEPROM memory. We have mini USB port which is used for powering up and duping the code.

IX. RESULTS & DISCUSSION
Here, the Arduino Nano is a control unit which accumulate all the ingredient concerning the herb/plant development, checking of temperature, rain and LDR sensor along with a small water tank dispatched for contributing enough quantity of H2O to plants, as well as in rainy season if plants wanted water as to survive we have a roof such as to open and close roof whenever we wanted. So as to supply water for plants we can control that particular roof by our self by using the Wi-Fi controller app in our smart mobile.
This whole system called IOT based greenhouse environment monitoring and controlling through sms alert can be controlled by worth of 5v power supply. LCD is located in this proposed system for giving enough content values like soil, temperature, LDR etc., therefore we are also created an IOT mobile app to keep all the updated details about the development of plants. LCD display expose the reading values of rain, temperature, soil moisture and LDR.
