Greenhouse is an advanced hortical facility which changes plant growth environment creating suitable conditions for plant growth.

Monitoring & control of greenhouse environment play an important role in greenhouse production & management.

This project consists of implementation of a WSN that can monitor the air temperature, humidity & ambient light intensity in greenhouse

The software which runs on a wireless network node deals with both application specific tasks and networking tasks (e.g.: assembling a message to send to another node).

The software on a node is organised as number of layers, forming a stack, with the user application at the top.

Wireshark is a network protocol analyser application. It is widely used for network troubleshooting and

analysis, software and communications protocol development, and educational purposes.

NXP provide dissector plug-ins to the Wireshark source code in order to add support for the their protocols.

FEATURES Sensors measure voltage, temperature, light and

humidity. Temperature can be measured in the range 0 to

124oC. Relative humidity can be measured in the range

0-100%. Node operates independently if the network is

lost. Display of the network shape. Creating log.

Terminal Output

15

The various wireless technologies studied in research are listed as under:

Bluetooth XBee PRO series 1 and 2 RF wireless device Wi-Fi device ZigBee

WIRELESS TECHNOLOGY

16

Why XBee? Based on IEEE 802.15.4

standard for Wireless Personal Area Networks(WPANs).

Data Rate: 250kbps per channel at 2.4 GHz.

Range : 10m to 1.5km. Availability. Low power sleep modes. Low cost. Flow control. Error control. Low power.( 3.3V @ 215mA)

Wireless chat

Wireless text chat going between two computers using XBee 802.15.4 Wireless Modules.

The text type to one XBee will be wirelessly transmitted to the other Xbee.

Graphical User Interface

21

PRIORITIZING GSM PHONE OVER GSM MODEM Easy to buy Battery operated Voice features Less Costly GSM mobile telephones and modems can be operated a serial

interface. A command entered at the user port generally begins with an

‘AT’ command prefix.

GSM TECHNOLOGY

AT Returns a “OK” to confirm that modem is working

AT+CPIN=”xxxx” To enter the PIN for your SIM ( if enabled )

AT+CMGF=1To format SMS as a TEXT messageRespoNse: OK

AT+CMGS=”+yyyyy” <Enter>> Your SMS text message here<Ctrl-Z>

To Send an SMS.The “+yyyyy” is your recipient's mobile number.

MANUAL SMS GENERATION

23

PORT SELECTION

24

Protocol for mail transfer between mail servers.

Goal : To transfer mail reliably and efficiently.

SMTP servers look at the destination address of a message and contact the target mail server directly.

DATABASE & LIVE GRAPHS

• A database with a set of real time data has been maintained and live graphs are being generated on the dashboard of GUI.

28

C# console application. Programmed in such a way that it reads the data from USB

serial port & gives the output.

Software as a SERVICE

29

AUTOMATIC SMS AND EMAIL GENERATION

A threshold value for temperature, humidity and light is pre-defined.

The live data obtained is compared to the threshold values, exceeding which leads to an automatic email and SMS notification generation.

Software as a SERVICE

30

EMAIL RECEIVED

31

INSERTION IN DATABASE

Live values of Temperature, Light and Humidity are being stored in the database along with the current date and time.

Prediction of “Weather” parameter is being done on the basis of current values received.

WEKA, is a computer program that was developed for the purpose of identifying information from raw data gathered from agricultural domains. It contains tools for a whole range of data mining tasks:

Data pre-processing Classification Regression Clustering Association Visualization

PATTERN GENERATION & AI

33

WEKA usually accepts .arff files, which are an extension of .csv files and specially supported by WEKA.

ARFF file Creation

34

Format of ARFF file

35

Studies how to automatically learn to make accurate predictions based on past observations.

Classification problems: Classify examples into set of given categories.

Often much more accurate than human-crafted rules (since data driven).

Don’t need a human expert or programmer. Automatic method to search for hypothesis explaining

data. Cheap and flexible- can be applied to any learning task.

Machine Learning Algorithms

36

Using the following Machine Learning Algorithms to test our data, we got the best and accurate result by J48.

ZeroR J48 NaiveBayes LMT

Hence, we did all the processing and other steps using the algorithm J48 that is best suited for data like ours.

Basic Scenario:

Controlling the circuit through parallel port.

Software using Userport dll to access the port.

Interfacing of circuit is done using DB-25 male connector.

41

Receive input from parallel port.

Maintain constant voltage level with regulator.

Maintain a switching mechanism mechanically with the help of relays.

Glow the appliances when any parameter (i.e. temperature, light or humidity) goes out of suitable range.
