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.
