Raspberry PI controlled SMS-Update-Notification (Sun) system

This paper explains a Raspberry Pi controlled SMS-Update-Notification (SUN) system. Raspberry Pi is a credit card sized single board computer with ARM11 microprocessor. Short Message Service (SMS) is one of the cheapest and best way for sending a message from mobile. Basic idea of SUN system is to notify updates to the people in a working environment from authorized persons at anywhere just by SMS. This task is accomplished by conjunction of GSM module with Raspberry Pi. Working procedure of this SUN system is only the authorized person can send SMS from anywhere to the SIM in GSM module.
