The paper is based on the National Undergraduate Electronic Design Contest—Liaoning area in August 2014. The design uses the TI company LDC1000 Inductor / Digital Converter Evaluation Board (AY-LDC1000)as a metal probe,STC89C52 single chip microcomputer as control core,stepper motor driver L298N,integrated voltage regulator 7805 and 7812 to constitute a driving circuit,and then develops a scanning metal detector.The experiment results show that the detection system not only has high detection accuracy,stable performance and easy to extend,but also can sim-plify system structure,reduce the scanning time,lower the cost of the system with mechanical structure design of scan-ning.And the overall performance of the system is enhanced through the sound-light alarm device.
