Introduction to Greenhouse

• Greenhouses are best controlled-area-environment
  to grow different plants.
• It is a building with mix of covering materials,
  such as a glass or plastic roof and frequently
  glass or plastic walls.
• Plant Growth Chamber is heated due to incoming
  visible solar radiation falling on the glass
  material which is transparent from the sun. These
  radiation are absorbed by plants ,soil, and
  other things inside the building and remains
  inside in the form of heat.

3. In turn, the glass absorbs the long
wavelength IR and warms up. The glasses in turn
emits long wave length IR, which is again
reflected back to Green House
1. Short wave length IR light from the sun passes
through the glass
3. Warmed objects emits long wave length IR
light
2. Objects inside the green house absorbs short
wave length IR light and becomes warmer

Automated greenhouse

• Greenhouses acts as an important part of the
  agriculture and horticulture sectors of a
  country.
• Green House are used to cultivate plants under
  controlled climatic conditions for optimal
  production.
• Auto Monitored greenhouse helps in the automatic
  monitoring and controlling of climatic parameters
  which effects the plant growth and their
  production.
• So to control the climate factors and environment
  autonomously , sensors and embedded controllers
  are required.

Relay to Turn ON/OFF Fluorescent Light bulb,
water Pump and fans

• DC voltage 5V
• DC current 500mA.
• Relay enables AC current to flow by implementing
  a switch within the device which is controlled by
  DC current.
• The relay is supposed to allow AC current through
  when no dc current is flowing.
• When DC current is passes through, relay will
  flick switch to ground, therefore causing open
  circuit for AC current flow.

Arduino IDE 1.0.1

• The Arduino integrated development environment
  (IDE) is a cross-platform app. written in Java,
  and is derived from the IDE for the Processing
  programming language and the Wiring projects.
• A program or code written for Arduino is called a
  "sketch".
• The Arduino IDE uses the GNU toolchain and AVR
  Libc to compile programs, and uses avrdude to
  upload programs to the board.

Output of the sensors

• Temperature sensor
• If the temperature exceeds beyond the limit set
  then a fan will be automatically switched
  ON as a coolant to reduce the
  temperature.
• When it reaches the desired temperature the fan
  will be switched OFF automatically with the help
  of a relay.
• But if the temperature decreases bellow the
  optimum temperature a bulb as a heater will be
  switched ON to set the temperature within the
  desired range.
•  
• Light sensor
• Light sensor sense the light and set an optimum
  light in the greenhouse for the plants.
• An artificial light will be switched ON
  automatically by the light sensor with the help
  of relay if there is insufficient light for the
  plants in the greenhouse
• And the light is switched OFF automatically when
  the plants get sufficient light from the sun.

• Moisture sensor
• Soil moisture sensor check the water present in
  the soil.
• If there is not proper water in the soil then
  moisture sensor sends signal to the water pump
  which as a result pumps up the water from the
  tank and provide sufficient amount of water to
  the soil.
• When the sensor senses the threshold value of
  water level in the soil it automatically turn OFF
  the pump.
•  
• Humidity sensor
• Humidity sensor is used to check the humidity of
  the air in the greenhouse.
• If the humidity exceeds the limit set then an
  exhaust fan will be switched ON with the help of
  relay to throw the humid air out of the
  greenhouse to maintain the suitable environment
  for the plants.
