When the student sends a sms through mobile to our control unit, gsm modem receives the sms. Here we can control the gsm modem by the AT (AUTOMATIC TELLER )Command . after getting the sms from gsm modem, it sends the messege to the controller unit.Level converter is used to convert the logic level.(i.e). gsm modem receives the sms in +12v logic. But it sends the sms to control unit via level conveter unit in+5v logic.
