The aim of the project is to provide the student’s marks to the user(parents/students/other person) mobile whenever the examinations are conducted any time during its course of study .During the time of admission the college provides a ten digit mobile number to the to know the academic marks of his son /daughter. At the end of the examinations and when the results are out, if any person want to know the marks of any student (he/she)has to send an SMS with Pin number to the ten digit mobile number provide by the college. Then he/she will receive an SMS regarding the concerned student academic marks from the college data base. The advantage of this project is that any person want to know the marks he has to send just an SMS. The main intention to design this kind of applications is to put the student’s thoughts and actions into right path.
To send the marks to the parent’s mobile, GSM modem is required. The modem provides the communication interface. It transports device protocols transparently over the network through a serial interface. The GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.
The project consists of the modules like GSM modem, microcontroller, the marks will be entered and saved in the PC and MAX232 used as an interface (voltage converter) between the modem and the microcontroller, microcontroller and PC. The data from the PC will reach the microcontroller through serial communication and will be finally sent to the user mobile through GSM modem.
