Abstract: This system detects the use of GSM mobiles in mobile restricted areas such as examination halls, hospitals and other do not disturb areas. The sniffer keeps monitoring the RF level in the area and gives a warning indication if the RF level increases due to mobile activities. This warning indication is send as a message through a GSM module and displayed on a LCD. The pic 16F877A Microcontroller contains internal flash memory of 8kb along with a large RAM area and internal EEPROM. To make it fit for monitoring and real time system applications microcontroller is induced with an 8 channel 10 bit A/D converter. Liquid crystals are materials that have a molecular structure and will flow like a liquid. It is also a low power device. Some properties of this molecular structure are associated with solids. An antenna whose receiving or radiating elements, such a arms of a dipole, are made in the form of an extensible system of metal tubes or rods of approximately equal length. Such a design facilities changing the length of antenna elements during tuning and permits the size of antenna to be reduced when it is not in operation for example during transport or storage. Telescopic antennas are used principally in conjunction with radio receivers, radio transmitter-receivers, portable television receivers and television receivers installed in moving objects. To make it cost effective and to have a small dimension SIM Com is induced with in a powerful single chip processor integrating AMR 926EJ-S core and quad band-GSM/GPRS module of SMT type. SIM Com contains a reliable wireless module-SIM900 and is ultra compact.
