The advent of wireless technology and advances in telecommunications has brought great advantage to the human society and helped to contribute to globalization. While this is laudable, the unauthorized use of this phone has contributed to some of the social vices seen in the society, such as examination malpractices, computer hacking, interference with sensitive health equipment, and organized crime within and outside correctional facilities. In a bid to curbing some of these excesses, a good mechanism is required to detect indiscriminate use of mobile phone in public places to avoid public indiscipline. In this work, a mobile phone sniffer is designed using appropriate computer aided design (CAD) tools multism 11.0.The code is written and embedded using Intel 8051 Microcontroller series. The sniffer can detect signals of all brands of mobile phones in an active mode and inform about the detected signals through a blinking Light Emitting Diode (LED) and a Buzzer.
