MARKS ANNOUNCEMENT SYSTEM THROUGH SMS
The aim of the project is to send the student’s marks to their parents mobile whenever the examinations are conducted. This application is carried on using wireless communication, GSM. At the end of the examinations and when the results are out, the marks of the students will be sent automatically to their parents mobile. Initially, the marks will be entered and save in the PC. Each and every student’s marks will be sent to the predefined mobile number. 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.
