project is designed to detect the mobile phone in a closed
room / place . where as this project is aimed to detect the
mobile phone where the mobile communication is strictly prohibited like hospitals

APPLICATIONSThis project is very useful for the confidential
meetings, secret occasions and other similar requirements
This can be can be used in nuclear plant Avoid any effect due to cell phone
Used in the military Camps, Defense establishments to prevent the information leaking.
So this project can be used in the hospitals to detect the mobile device

FUTURE SCOPE
the project also incorporates a vary unique feature of remote paging & indication. In this part when the project is installed on the frame of a door or entrance, It scans incoming person’s mobile and if the person is carrying an mobile phone, then instead of activating an alarm, it sends a wireless message using Infra-Red signal to a Microcontroller unit which is monitored by a person.

CONCLUSION
By using this project detect the mobile phone in a closed room / place
This project is very useful for the private meetings, defense establishments, military camp, Hospitals; Petrol pumps etc., where the uses of an Mobile Communication device are prohibited.
