Abstract

This research has been done to improve the performance of monitoring system by introducing communication device to notify user the situation or condition of monitoring system.This will improve productivity of the system by reducing human effort and introduce human to technology nowdays.For this project,GSM modem which is a modem that allow a SIM card to allow it work like mobile operator such a phone is introduce as communication device to deliver the information from monitoring system to user via SMS.GSM is a multitasking modem that can deliver message,receive message and store message.GSM modem can be connected using USB or Bluetooth but Bluetooth only cover in short range.GSM modem developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) cellular networks used by mobile phones,first deployed in Finland in December 1991.GSM networks operate different number of carrier frequency ranges with most 2G GSM networks operating in the 900 MHz or 1800 MHz bands.Where these bands were already allocated, the 850 MHz and 1900 MHz bands were used instead.In rare cases the 400 and 450 MHz frequency bands are assigned in some countries because they were previously used for first-generation systems. So,GSM modem advance technology that always improved by time.
