GREEN HOUSE AUTOMATION USING ANDROID APPLICATION

-In recent past, the environment has played an adverse role in the life of humans as well as vegetation. More or less, the direct impact of this comes up on the economy of a country. Uneven weather condition leads to uncertain farming and also leads to cultivation damage. This has prerequisite to protect and cultivate the produce in a controlled environment along with automation. The very idea leads to the invention of greenhouse with automated features . A greenhouse is an enclosed system made up of special glass material which encloses vegetation grown inside it and thus provides protection from various hazards of environment. The green house traps the heat radiation from the sun and retains that heat inside the encloser. The project aims at automating the various parameters of green house such as temperature, moisture, humidity, ventilation, drip irrigation, security etc automatically. Whether to actuate a particular system or not depends on the desirable limits as set by the end user. Further, the entire control of the greenhouse could be done through an android application. The user sitting at distant place can control the temperature, water tank, drip irrigation, pesticides as and when desired through the application.


Fig1: Open field cultivation
Lack of rain. [11] A study was conducted to determine the yield and quality of 'Dwarf Cavendish' banana, cultivated in open fields and also in protected (plastic greenhouse) cultivation. The site is located in the central south coastal region (altitude 50 m, latitude 36°33'N) of Turkey. Results obtained in all the qualitative and quantitative parameters clearly indicate that bananas grown in protected cultivation are superior to those grown in open-field cultivation, with a yield increase of 53% [1] . Similar results were obtained by Eckstein et al. (1998) and Galan Sauce et al. (1998). Eckstein al. (1998) stated that inside the greenhouse, plants were 34% taller and pseudo stem circumference was 4% greater at flowering stage compared with open field plants. [1] C. GREENHOUSE VS AUTOMATED GREENHOUSE An unautomated greenhouse proposes several difficulties in handling and maintaining the system. Moreover it also yields to increased man power. In order to have a coherent production, the florae needs continuous and timely water supply. The proper dose of the nutrients and pesticides yields to increased growth. And therefore in an unautomated greenhouse, personal monitoring is required to be the given to the cultivation. However by automating the various parameters of the greenhouse, the above difficulties could by mitigated. Automation also brings in better accuracy, reduced man power and more reliable system. This utility model mainly focuses on automating various factors of the greenhouse such timely supply of water, temperature control inside the greenhouse, moisture content in the soil, periodic sprinkling of the fertiliser and pesticides, system security etc. Furthermore, it also focuses on controlling the entire network through an android application. This facilitates the user to monitor and operate the system sitting at distant place.

Open Cultivation Automated Green House
Individual is required to water the plants.
As per the requirement of plant, the automatic watering to plant is given. Temperature is not controlled.
Temperature gets controlled automatically Labour cost is more.
Initial cost is much high. Plantation gets affected by animals.
Plantation does not get affected by animals.
No Security to plantation. Security to plantation is provided. On site presence is required Can be controlled and automated sitting at distant place.

Human labour increases
Automation leads to less human efforts except a technical expert. Quantity of plant cultivation is fine.
Quantity of plant cultivation is further increased. Tomato growers had a mean income of KES 188,591.67. [7] Tomato growers had a mean income of KES 345,920.83. [7] .

III. SYSTEM BUILDING
The system comprises of the an input unit, communication unit, control unit, detection unit , display unit and execution unit. The control unit is the main processing unit. It drives the execution unit as per the command given by the input unit. The detection unit consist of temperature sensor, water level sensor, moisture sensor, ir sensor and real time clock. The LCD displays the current status of the various system laid inside the house such as whether the drip irrigation system is on or off, whether the temperature in under prescribed limit or not. If not, then whether the cooling system is actuated or not etc. The input is given by the user in the application installed in the cell phone. The command is then communicated to the controller through wifi module. The controller executes the command in the actual system. The data from the different sensor is monitored by the controller to determine the normal operating condition. This data which is fed back to the controller is then printed as a message inside the application. For example,if the temperature limit is violated, the cooling system gets activated. And hence, a message will be shown in the application about the activation of the cooling system. Thus in the automatic control system, the growth environment in the shed can be detected in real time, moisture, other nutrients required by plants are supplied and controlled intelligently. Moisture level sensor is used to check the moisture content in the soil [2] . Whenever the Moisture content in soil gets lower, the drip irrigation system gets turn on and water is supplied in the field. When moisture content goes high (as set by the end user), the irrigation system is turned off. Thus in this way Automatic watering to the plant as per requirement is given. Also its status is displayed on LCD as well on Android Mobile. 3rd Module: Automatic Pesticide Sprinkling At beginning the soil is tested and for its better growth the types of pesticide and the amount in which is should be sprinkled is decided. Based on this, a particular time is decided in which pesticide are sprinkled for particular period. This is monitored by a real time clock(RTC). It actuated the sprinkling mechanism for a definite time as suggested by the user. 4th Module: Automatic cooling system Every plant grows under certain temperature conditions. An agronomist decides this criteria which is then maintained inside the greenhouse for the efficient growth of plants. For this the temperature sensor is used [2] . If temperature goes beyond some limit which is not suitable for plants then the cooling system (Fan) gets turned on and the internal heat in the greenhouse is extracted out. Thus maintaining a suitable temperature in greenhouse. To make the greenhouse attractive and to promote it, the glorious illumination system is adopted. At night for vision as light is necessary so LDR is used and as per necessary the illumination is lit up. [4] 7th Module: Android mobile application It is "The heart" of the project. For better reliability, making system more effective and user friendly, Android Mobile application is made. Each and Every parameters of greenhouse is analysed and can be controlled through this app. We have used Wifi module for it [4] . This enables a user to operate and monitor the system sitting at distant place. CONCLUSION Greenhouse Automation is an area which has a wide scope of growth. Automation is one such area enabling the user to have more reliable, accurate and economical system on a longer span of time. This utility model emphasis on automating each and every parameter inside the greenhouse. The present day industries focus more on modernisation and customer satisfaction. And larger part of India's economy is dedicated to the agriculture business. So more or less, this model comes morehandy and serves a larger purpose to the industry as a whole.
