Gsm Based Datalogging System
Abstract
The ability to record data from events and view the results at a place far away from where the
event is occurring is very essential and can be applied in many areas such as weather stations
to monitor various climatic conditions, industries to monitor changes in industrial processes
and to record changes in laboratory experiments. This project handles the design and
implementation of a system that reads analog or digital voltage from the output of a sensor.
The sensor output voltage must satisfy the conditions that Ov represents the lowest value of
the event to be monitored, 10v represents the highest value of the event to be measured and
the voltage output of the sensor is linear for all values ofthe event to be measured. The
voltage output is attenuated, using a signal conditioning circuit, to a voltage range compatible
with the MSP430G2553 microcontroller. The MSP430G2553 converts the conditioned
voltage signal to a decimal number and sends the decimal number through a G.P.R.S. module
to a PHP server. The PHP server processes the data and displays the results on a website
which can be accessed by a user over the internet
