- 2. What is a green house? Green houses are used to grow plants in controlled conditions These green houses are usually build in houses with glass or plastic in which plants will be grown in controlled conditions
- 4. AUTOMATED GREEN HOUSE. Green houses 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 solutions. Automated green house involves the automatic monitoring and controlling of climatic parameters which directly or indirectly govern the plant growth and their production. In order to control the climate factors and environment automatically we require a software.
- 5. ABOUT THE SOFTWARE: The software used here is Keil uversion3.It is an integrated development equipment that helps you write compile and debug embedded programs. It encapsulates the following programs: A project manager. Tool configuration. Editor Powerful debugger.
- 6. OBJECTIVE: Build miniature green house which is equipped with automatic monitoring and controlling system. Constantly monitor and control environmental conditions in green house to ensure it remains at present temperature , light, moisture and humidity levels. It focuses on saving water ,increasing efficiency and reducing the environmental impacts on plants production. The user can see the atmospheric conditions of the green house plants on website and control the green house from far away places.
- 8. WORKING OF MICRO CONTROLLER: DEF:A control device which incorporates a micro processor. A microcontroller is a general purpose device, but that is meant to read data, perform limited calculations on that data and control its environment based on those calculations. The prime use of a microcontroller is to control the operation of a machine using a fixed program that is stored in ROM and that does not change over the lifetime of the system. 8051 micro controller has 40 pins which are having their specific functioning.
- 9. EMBEDDED SYSTEMS: An embedded system is a system which is going to do a predefined specified task is the embedded system and is even defined as combination of both software and hardware. A general-purpose definition of embedded systems is that they are devices used to control, monitor or assist the operation of equipment, machinery or plant. . "Embedded" reflects the fact that they are an integral part of the system. The very simplest embedded systems are capable of performing only a single function or set of functions to meet a single predetermined purpose.
- 10. LIGHT DEPENDENT RESISTOR: A Photoresistor or light-dependent resistor(LDR) or photocell is a light-controlled variable resistor. The resistance of a Photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. Photoresistors come in many different types. Inexpensive cadmium sulfide cells can be found in many consumer items such as camera light meters, street lights, clock radios, alarms, and outdoor clocks. They are also used in some dynamic compressors together with a small incandescent lamp or light emitting diode to control gain reduction. A light dependent resistor is a small, round semiconductor.
- 12. POWER SUPPLY: A power supply is a hardware component that supplies power to an electrical device. receives power from an electrical outlet and converts the current from AC (alternating current) to DC (direct current). An AC source, a transformer, and a bridge rectifier (full diode bridge) can turn an AC “wall” source into a usable DC source for low –voltage electronics. It also regulates the voltage to eliminate spikes and surges common in most electrical systems. Power supplies are rated in terms of the number of watts they generate.
- 14. RELAYS: A relay is an electrically operated switch. These are remote control electrical switches that are controlled by another switch, such as a horn switch or a computer as in a power train control module, devices in industries, home based applications. Relays allow a small current pin, 4-pin, 5-pin, and 6-pin, single switch or dual switches. Relays are used throughout the automobile. Relays which come in assorted sizes, ratings, and applications, are used as remote control switches. A typical vehicle can have 20 relays or more.
- 16. THERMISTOR: A thermistor is a type of resistor whose resistance varies significantly with temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor.
- 17. LIQUID CRYSTAL DISPLAY(LCD): A liquid crystal display (LCD) is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. 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
- 18. SENSORS: In this project sensors play a very important role. here we can use various sensors like light sensor, temperature sensor, humidity sensor etc. LIGHT SENSOR: A light sensor as its name suggests ,is a device that is used to detect light.
- 19. SENSORS: TEMPERATURE SENSOR: temperature sensor is also called as thermistor. Thermistors are thermally sensitive resistors whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body temperature.
- 20. SENSORS: HUMIDITY SENSOR: Humidity is the presence of water in air. The amount of water vapor in air can affect human comfort as well as many manufacturing processes in industries.
- 21. ADVANTAGES: Increase fertility. Better productivity. Increase in quality of crop. Percentage of germination of seeds is high in green house.
- 22. FUTURE SCOPE: The system which we are discussed above is implemented on the board and results are shown. But the system can work more efficiently with present technology and may improve the existing technology in the field of wireless communication and with the wide improvement of GSM technology which can improve Short Message Service with the help of embedded technology anything may become possible and easy.
- 23. CONCLUSION: With the wide improvement of wireless and GSM technology. The system may be cost with wireless sensors may little cost but it works with more effectively. The system may be implemented with the help of many technologies but these technologies more reliable, easy to implement, works effectively and easy to operate.
