GREEN HOUSE DIY AUTOMATIC MONITORING AND CONTROLLING system in greenhouse By Huzaifa Ujjainwala- R&D Head Meditech Technologies India Pvt Ltd. www.newmeditech.com


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 3. Warmed objects emits long wave length IR light

1. Short wave length IR light from the sun passes through the glass

2. Objects inside the green house absorbs short wave length IR light and becomes warmer

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. By Huzaifa Ujjainwala- R&D Head,, Meditech Technologies India Pvt Ltd.. www.newmeditech.com


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.
