Introduction
•What is a Greenhouse?
• Greenhouses are controlled-area-environment to grow plants.
• It is a structural building with different types of covering materials, such as a glass or plastic roof and frequently glass or plastic walls.
• It heats up because incoming visible solar radiation (for which the glass is transparent) from the sun is absorbed by plants ,soil, and other things inside the building.
Automated greenhouse
• Greenhouses form an important part of the agriculture and horticulture sectors of a country.
• They can be used to grow plants under controlled climatic conditions for optimal production.
• Automated greenhouse involves the automatic monitoring and controlling of climatic parameters which directly or indirectly govern the plant growth and hence their production.
• In order to control the climate factors and environment autonomously ,it is required a computer/software equipment.
What is a Automatic roof ventilation of smart
greenhouse ?
Automatic roof ventilation of smart greenhouse
a system that serves to balance the temperature in the room greenhouse by opening the ventilation on the roof of the
greenhouse automatically
purposeTo facilitate the work of man. Which can be applied to smart greenhoue based arduino but
effective cost

Tool and material
Arduino Uno
Arduino/Genuino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.

PCB
Tool and material
A printed circuit board (PCB) mechanically supports and electrically connects electronic component using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Components – capacitors, resistors or active devices – are generally soldered on the PCB. Advanced PCBs may contain components embedded in the substrate.

The challenge of this project
We have some problems with our project the first problem is uniting program become one program arduino and the last problem that we faced is how to make an interesting
prototype design to cover our project.
