Design and Implementation of Shift Frequency Measurement System for Metal Detector

Abstract:

Metal detectors are widely used to find embedded metal within objects which are beyond eye site. This study concerns the design and implementation of frequency counter with 4 digits seven segment LED display for metal detection system using PIC microcontroller. New algorithm for frequency counting is developed. The software is also developed to detect the shift frequency measurement from the VCO output. The corresponding frequency at the VCO output of Induction Balance Metal detector is clarified. The experimental results of this research revealed that using PIC16F628A for frequency measurement system is able to provide very high accuracy for metal detection application. Additionally, the proposed system is the cost effective, less circuitry, high performance control system and feasible for many other metal detection applications.
