Mobile phone restrictions are highly encouraged in examination halls, hospitals and other restricted
areas. Instead of checking manually, this detector will ease work. Metal detectors are not only used for security
purposes but also deployed in food production industries where accidentally food is contained with metal. It can be
also used for detection of antiquities. In this work, we have proposed a hybrid detector named Hidden Mobile Phone
and Metal Detector(HMPMD) which detects hidden mobile phones as well as metals to enhance safety measures in
examination halls, prisons and even for surveillance applications, where the information has to be kept highly
confidential.
