2. Backround :
๏ต CO2 is a gas that is colorless, tasteless and does not stimulate, the source of
CO2 gas comes primarily from the burning of petroleum, coal and natural gas.
๏ต As long as humans are still using wood fuel, increase the levels of carbon
dioxide gas in the air can be ignored.
๏ต With the population growth rate increases the range of human needs, such as
food, housing, lighting, and transportation. That means the procurement of
fertilizer, agro industry, electric power, and transportation industries is
increasing, so that the fuel requirements are also increasing. As a result, the
production of more and more carbon dioxide into the air in industrial areas.
3. Description Project
Project we make is a detector co2 (carbon dioxide) to give the air intake to
the plant so that the plant remains fresh so stay awake and grow well, and we
make this tool using arduino uno as tools so that we can make this project.
4. ๏ต Arduino is a computer hardware and software company, project, and user
community that designs and manufactures microcontroller kits for building digital
devices and interactive
๏ต MQ-135 gas sensor is a hazardous gas detection apparatus for the family, the
environment, suitable for ammonia, aromatic compounds, sulfur, benzene vapor,
smoke and other gases harmful gas detection, gas-sensitive element test
concentration.
Tools used
5. ๏ต LCD (liquid crystal display) is the technology used for displays in notebook and
other smaller computers. Like light-emitting diode (LED) and gas-plasma
technologies, LCDs allow displays to be much thinner than cathode ray tube (CRT)
technology.
๏ต Buzzer Electric is an electronic component that can convert electrical signals into
sound vibration.
6. ๏ต A Relay is an electrically operated switch. Many relays use an electromagnet to
mechanically operate the switch and provide electrical isolation between two
circuits. In this project there is no real need to isolate one circuit from the other,
but we will use an Arduino UNO to control the relay.
๏ต Transformer or often abbreviated with the term transformer is an electrical
device that can change the level of an AC voltage level to another. The purpose of
changing the level of such as lowering the AC voltage of 12 VAC or 220VAC to raise
the voltage of 110VAC to 220 VAC.).
7. ๏ต Light Emitting Diode or LED is often abbreviated with electronic components that can emit
monochromatic light when a given voltage is developed. LED is a family of diodes made of
semiconductor materials.
๏ต Connector Male vs. Female: Male connector is the side of a connection that has prongs - like
the power plug on your computer monitor. The side that runs from your monitor to the wall is a
male. Outlet is the female connector.
12. Conclution :
๏ต Of the project that we create can be conclude that the CO2
greenhouse is very important. Because CO2 is food for plant, and
which carry the essentially all plant on earth or the sea. And the
more CO2 they eat (air or water absorbsing) the bigger and better
for them .
