Abstract- Many organizations, scientific institutions
and government agencies are installing monitoring
stations to monitor weather data and tides data as
raw data for weather forecasts .However these data
are still scattered on separate systems. Therefore
interested parties are still difficult to access all the
data. This paper propose the design of data center for
weather and tides monitoring located in several
operational databases. As weather is the statement of
the physical conditions at an instant, forecasting is
related to all living creatures all over the world. In
this 21st century, weather monitoring and forecasting
have great importance and is used in several areas
such as keeping track of agricultural field weather
conditions to that of industrial conditions monitoring.
Weather monitoring would help in keeping record of
different climatic behaviors which includes wind
speed, wind direction, temperature and humidity.
Weather Monitoring System can either be wired or
wireless one. Just in case of wireless communication,
the connectivity will be more user friendly and
weather monitoring would not require physical
presence of the person at the remote location.
Wireless communication is the transfer of
information over a distance without the use of wires.
The distances involved may be long. GSM module is
the cheapest and the most convenient technology now
being used for wireless communication. The wireless
weather system fundamentally requires few basic
modules such as GSM module, sensors and
microcontroller module, display module..
Key Words: GSM, Base station.
1. INTRODUCTION
The main objective of this project is to transmit data
from VAISALA weather transmitter sensor WXT520 to
the control room for weather monitoring and
forecasting. Wireless communication is the transfer of
information over a long distance without use of any
wired media. The distances involved may be long or
short. GSM module is the cheapest and the most
convenient technology now being used for wireless
communication. In this we transmit real time data
wirelessly through GSM over a long distance. This
system fundamentally requires few basic modules such
as GSM module, sensors, transmitter and receiver
module. One sensor measure six weather parameters
which is input to data logger. Vaisala weather
transmitter WXT520 sense the parameters like wind
speed, wind direction, precipitation(rainfall),
atmospheric pressure, temperature, relative humidity.
Weather plays an important role in the operation of
industries and various facilities in the world. As weather
is the statement of the physical condition of that instant,
so forecasting the weather is of related to all living
bodies on the earth. Forecasting can be done in two ways
globally or region based. The region based forecasting
over a small area is much more accurate and of high
resolution while global based are not much accurate but
better forecasts for long-range. Meteorology had a close
relationship with human survival and producing
activities. With the development of economy and
technology, and with the gradual implementation of
national sustainable developmental strategy, it requests
higher and higher standard of Meteorological monitoring
and the demand is also growing. Automatic weather
station can collect meteorological parameters near the
specified place automatically, such as temperature,
humidity, air pressure, wind speed, wind direction,
visibility, etc., and calculates and saves these parameters
and transmits to the central computer needless of the
guard of person. GSM public networks can be popularly
used, and the encryption technology is mature, so it can
be used economically and practically. The system
transmits data through[2]
2. SENSOR
WXT520 the Vaisala Weather Transmitter WXT520
measures barometric pressure, humidity, precipitation,
temperature, and wind speed and direction. To measure
wind speed and direction, the WXT520 has the Vaisala
WINDCAP® Sensor that uses ultrasound to determine
horizontal wind speed and direction. The array of three
equally spaced transducers on a horizontal plane is a
Vaisala specific design. Barometric pressure,
temperature, and humidity measurements are combined
in the PTU module using capacitive measurement for
each parameter. It is easy to change the module without
any contact with the sensors. The WXT520 is immune to

flooding clogging, wetting, and evaporation losses in the
rain measurement.[5]

3. DATA LOGGER
In this project we are using 3000C series data
logger for storing data coming from sensor. The 3000C
Series has three versions with 8,16 or 24 Analog Input
Channels, corresponding to Models 3008CM, 3016CM
and 3024CM. It consists of following basic elements:
microprocessor, protection circuits, communication
modem, Power Source, Display and keyboard, Terminal
Strip for external connections.. Connections with the
sensors and other external components such as the
communication antenna, the solar panel, a radio-modem
etc., can be made using specific accessible connectors on
the outside of cabinet, which permitting a quick
connection that is useful when working with
transportable stations. It has also has provision of RS232
serial connection for transmission and reception of data.
The 3000C remote units were designed using the
electronic components with a high level of integration,
combining the following in a single 6 layers circuit board,
SMD technology which are necessary for the specific
required functions.[]
4. GSM SYSTEMS
To transmit weather parameters from remote location to
control room GSM wireless standard is used. The GSM
used in the proposed system is SIM900 which is a
complete quad band GSM/GPRS solution. It delivers 850,
900, 1800, 1900MHz performance for voice, SMS, data,
and fax in small factor in low power consumption. In the
proposed system, SMS facility is used; therefore 900MHz
frequency is used. The Modem is designed with 3V3 and
5V DC TTL interfacing circuitry, which allows User to
directly interface with 5V Microcontrollers (PIC, AVR,
Arduino, 8051, etc.) as well as 3V3 Microcontrollers
(ARM, ARM Cortex XX, etc.). The baud rate can be
configurable from 9600-115200 bps through AT
(Attention) commands. This GSM/GPRS TTL Modem has
internal TCP/IP stack to enable User to connect with
internet through GPRS feature. It is suitable for SMS as
well as DATA transfer application in mobile phone to
mobile phone interface. The modem can be interfaced
with a Microcontroller using USART (Universal
Synchronous Asynchronous Receiver and Transmitter)
feature (serial communication).
5. LITERATURE SURVEY
We will survey briefly in this section on the various
literatures making the use of GSM and other technologies
for weather monitoring usage.
In existing system the data from data logger is
collected by pen drive and from pen drive it will take
once in one month or once in two month, so it is
necessary to continuously take data for day to day
analysis purpose during forecast. For taking data
manually go to the forest area & copy that data from
pend drive to avoid this we have design a system
which wireless transmit data continuously to
control room from sensor located at forest area.(ref
1,2)

6.PROPOSED METHODOLOGY
The proposed system is consisting of the two
modules, one from which will be at remote location and
the other will be in the control room. Following block
diagrams are of these modules.
SOFTWARE USED FOR WEATHER FORECASTING

from transmitter module. This software gives output in
the Excel sheet format and also shows graphical format
of various weather parameter like wind speed ,wind
direction, temperature, humidity, barometric pressure,
precipitation(rainfall).

CONCLUSION
In this project work we have studied existing
system and working on this module using a PIC
microcontroller and ARM. This work includes the study
of sensor (WXT520) and data logger (GEUONICA CM
3000C series) along with their opreating principle
,working and features.
This module is not limited for any particular
application, it can be used any where in a environmental
forecasting industries with little modifications in
software coding according to the requirements. This
concept not only ensures that our work will be usable in
the future but also provides the flexibility as needs
change.
