GSM Modem Based Data Acquisition System
Abstract:
GSM Modem Based Data Acquisition is a process control system. It helps in collecting data from various processes
present at distant places. It helps one to monitor parameters like temperature, rainfall, humidity etc. the Service
personnel need not to visit distant sites for data collection .the data is collected automatically formed a data base and
stored in a PC. It can be used in industries as well as in home automation. This system uses AVR microcontroller AT mega
644P. The inbuilt ADC receives analog data from sensors and converts it to digital data and passes it to the
microcontroller. The sensors continuously send data from the distant site. This system is interfaced with a GSM modem.
Data acquisition, logging and analysis is an all important aspect and an indispensable tool in information systems
and communication technology. This work presents a system that is capable of providing a mechanism for sensing analog
signals and coding them into a digital device which also enables the data to be logged periodically while also alerting and
recording the status of any given physical quantity at intervals thereby ensuring no redundancy or lag in the acquisition
system. The work aims at the implementation of a low cost but efficient and flexible GSM protocol, used in any
environment to create a real-time data log. It is designed in such a way to achieve faster data acquisition and log time
through the use of acknowledged communications between devices rather than the manually outdated passive methods.
Thus this paper presents a system that is location independent, continuous, real time, speedy recording and logging of any
given physical quantity which ensures complete elimination of lags and errors irrespective of the volume of data involved.

The global system for mobile communication (GSM) is
a digital wireless technology standard based on
the notion that users want to communicate wirelessly
without limitations created by network or national
borders. In a short period of time, GSM has become
a global phenomenon. The explanation for its
success is the cooperation and coordination of
technical and operational evolution that has created
a
virtuous circle of growth built on three principles: Inter-
operability based on open platforms, roaming, and
economies of scale. GSM standards are now adopted by
more than 200 countries and territories.Modern

,enterprises rely on their data acquisition or their
existence. The data log is the lifeline of many
organizations, technological and human processes. Data
loss or mismanagement translates to potential
disastrous loss of critical and sensitive information,
technological efficiency as well as system confidence
and productivity.
The general method of data acquisition is manual, a
process that could be both time and labor wasting.
Manual method of data acquisition is generally costly
and error-prone as man is susceptible to fatigue,
carelessness, negligence and mistake. With a
traditional stand-alone data logger, you must first
record

, the data and then manually transfer it to a PC
before you can import it into a spreadsheet program
or
other tool to graph and visualize the data. Weather
agencies commonly keep temperature logs for a
number of locations, with temperatures being taken
several times a day, year round. These logs are used
to provide general temperature data, and for the
purpose of weather forecasting. Information about
temperatures can be useful for people who work
outdoors, and for people like farmers and gardeners, for
whom prevailing temperatures are a concern when it
comes to scheduling planting and this need cannot
be manually met.
