ABSTRACT
This project present the design and construction of a micro-controller based metal and mobile phone detector for security and control purposes. The metal detecting systems is a microcontroller based system. This metal detector make use of microcontroller for it operation as well as other components such as: comparator, voltage regulator, operational amplifier. transistors etc .. For this project, the metal detector is built in a way that a metal sensor (culprit oscillator) senses any electrically conducive metal or metallic object brought close to it. The sensor sends the signal to the microcontroller which processes the signal and turns on the driver (a de motor) connected to the door. Also present is an alarm and a Liquid Crystal Display (LCD) indicating the status of operation of the system. The power supply unit is dual in the sense that the circuit can be powered by electricity or battery and the battery charges when the circuit works with electricity.
