Cell Phone Operated Mobile Bug Using Microcontroller

Abstract: Now a days the most problem of world is unauthorized use of mobile phones in prohibited areas like confidential rooms, prisons, colleges, schools, hospitals, petrol bunks etc. There is great need to limit the use of cell phone at particular places and at particular times. Hence, the use of intelligent mobile phone detector is guaranteed. The main scope of this project is to develop an embedded system, which is used to detect the use of mobile in our surrounding using microcontroller and sends information to monitor section using zigbees. The objectives of the system are- To develop an embedded system, which is used to detect the mobile in our surrounding using microcontroller and sends information to monitor section using zigbees. To prevent use of mobile phones in confidential rooms, etc.
