The project titled "Pulse Induction Based Metal Detector" presents the design and implementation of a metal detection system utilizing two coils and voltage difference measurement. The system incorporates a microcontroller to generate pulses that are transmitted through a primary coil, inducing an electromagnetic field. The secondary coil receives the reflected pulses, and the voltage difference between the two coils is measured and analyzed. The primary objective of the project is to detect and identify metal objects based on the analysis of the voltage difference between the transmitted and received pulses. By measuring the variation in voltage caused by the presence of a metal object, the system can effectively detect and differentiate between different types of metals. The project emphasizes the optimization of detection accuracy by employing advanced signal processing techniques and calibration methods. The microcontroller precisely measures the voltage difference and applies appropriate algorithms to classify and identify metal objects. The proposed metal detector has broad applications in fields such as security screening, industrial quality control, and archaeological surveys. Its pulse induction technology, combined with voltage difference analysis, enables the detection of concealed or buried metal objects with high reliability. The project implementation involves the integration of hardware components, including a microcontroller, transmitter and receiver coils. Software algorithms are developed to control the microcontroller, process the received signals, and perform voltage difference calculations. Experimental results demonstrate the effectiveness and accuracy of the pulse induction based metal detector using voltage difference measurement. The system achieves reliable metal detection and identification, accurately differentiating between various types of metals based on their unique voltage signatures. In conclusion, the "Pulse Induction Based Metal Detector" project offers an innovative and efficient solution for metal detection applications. By utilizing two coils and measuring the voltage difference, the system achieves reliable and accurate metal detection, making it a valuable tool in diverse industries and scenarios requiring precise metal identification.
