Implementing an integration of cell phone detection, visual and SMS alerts, with remote jamming capabilities using a microcontroller as the central control hub is necessary following the imminent security risk factors associated with the unrestricted use of GSM phones in some areas. This work improved the restriction methods already employed by security experts in prohibiting the excesses of phone usage. The system performs continuous scan for GSM signals, sends information to a designated phone line upon detection of any signal within the allocated spectrum for MTN, GLO, 9Mobile and Airtel mobile (example in Nigeria) telecommunications network service providers. A jammer circuit is also integrated into the system to disable use of mobile phones within prohibited range. The jammer circuit can be activated remotely via SMS from a designated mobile phone. All the sequence of events is displayed on an LCD for effective monitoring. The ATmega328 is employed as the central hub of the system because it is a low-power, high performance AVR RISC-based microcontroller with adequate minimum requirement for the system execution. With carefully prepared instructions in C programming language the Microcontroller Unit is able to handle multiple events at the same time thereby controlling LCD displays, SMS messages and jamming unit of the system. The execution the circuit was successful in all of the proposed areas of deployment. Testing showed that all the GSM service networks were successfully detected and jammed within the radius of coverage specified in the design objective. The remote jamming was also implemented to add flexibility to the device. Hence, the jamming unit of the system can be activated from any location within the coverage of mobile telecommunication services. Deploying this system will eliminate the need for human presence in every location where phone use is prohibited.
