Pneumatic Metal Detection & Sorting System Using Micro controller

Abstract

This project presents the design and construction of a Pneumatic Metal Detection and Sorting System utilizing a microcontroller. The system is designed to automatically detect metallic objects from a conveyor belt based on their material composition. This automated machine controlled by an Arduino Pro Mini and Proximity Sensor, efficiently separates metal & non-metal pieces, placing them in a bucket. Results demonstrate accurate sorting with a reasonable good average time. Components include SMPS, Relay, IR Sensor, DC Gear Motor, Air Cylinder, Air Compressor and Pneumatic Solenoid Valve. The system offers potential applications in recycling plants, manufacturing facilities and quality control processes. This project showcases the integration of electronics, sensors and automation to enhance industrial processes and reduce manual labor, contributing to increased productivity and efficiency.
