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

APPLICATIONS
 This 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.
