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.

Programming of Arduino
  • The Arduino Uno is programmed with the Arduino
    software IDE .
  • The Atmega328 on the Arduino Uno comes preburned
    with a Boot loader which allows to upload a new
    code without the use of an external hardware
    programmer.
  • Arduino can also be programmed by bypassing the
    Bootloader and microcontroller through the ICSP
    (In-Circuit Serial Programming) header.
  • Arduino IDE is supported on windows , linux and
    Mac lion X platforms.

Humidity Sensor
  • A humidity sensor, also called a hygrometer,
    measures and regularly reports the relative
    humidity in the air.
  • Humidity sensor SY-HS-220 is used to sense the
    humidity of the air in the green house.
  • The warmer the air is, the more moisture it
  • can hold, so relative humidity changes
  • with fluctuations in temperature.
  • Operating temperature 5C to 45C
  • Humidity Measurement Range 5RH to
  • 95RH.
  • If the humidity exceeds the maximum limit
  • then the exhaust fan attached with Arduino
  • will be switched ON automatically.

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.

Technologies India Pvt Ltd.. www.newmeditech.com
37
  • 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.
