2. INTRODUCTION:
A green house is where plants such as flowers and
vegetables are grown. Greenhouses warmup during the day
when sun-rays penetrates through it, which heats the
plant,soil and structure. Green houses help to protect crops
from many diseases, particularly those that are soil borne
and splash onto plants in the rain.
This project demonstrates the design and implementation of
a various sensors for greenhouse environment monitoring
and controlling.

5. Working Principle
A greenhouse system in which there are four sensors.
These sensors act as input to the micro controller system.
The input feed provided to the micro controller is in the form of
analog data.
This data is converted by the controller into digital format.
The data is shown on the LCD display and also on the android
phone via Bluetooth.
6. Cont....
Thus the monitoring of temperature, moisture and other parameters
is done automatically.
Once the parameter values are monitored they can be controlled by
the embedded system which is built with coding. This is automating
controlling system. The android phone is operated by the user. The
android application is used for controlling as per the user knowledge
and required output.
7. Cont....
This greenhouse control system is powered by Atmega328
microcontroller it consists of temperature sensor, light sensor, soil
moisture sensor, LDR sensor, LCD display module, 12v DC fan, Bulb
and pump. Temperature sensor, senses the level of temperature., if it
goes high DC fans gets on and when the temperature goes low the
fan gets off. Soil moisture sensor, senses the water level as the level
decreases the pumps gets on. In the absence of light, the LDR
sensor senses and the bulb starts glowing. By this way it will become
easy to monitor and control the system.
8. Applications
A versatile wireless sensor system can help you monitor and
control many parameters of greenhouse conditions and
environments. You can measure critical conditions such as
Temperature,
humidity,
light,
air quality, soil moisture, irrigation water leaks, fan failure, HVAC
system performance, and more.
9. Advantages
One of the primary benefits of IoT-driven greenhouse
monitoring is the ability to collect real-time data on crucial
environmental parameters.
Sensors can be deployed throughout the greenhouse to
measure variables such as temperature, humidity, light levels,
soil moisture, and CO2 concentration.
