Abstract

A new metal detector is designed.Using LDC1000 digital inductance sensor and self-made coil as the metal detection sensor, based on eddy current principle. When the metal near the coil, because of the mutual inductance, the LC oscillation circuit's frequency changed, the changed frequency can be converted to the digital output data, through the SPI interface send to STM32 for process and display. When the test value exceed threshold value, will cause sound and light alarm. The test metal can detect 0.6mm diameter of thin wire. Can be used to food processing security check and other fields. Added Bluetooth and wireless communication, it can be used for the web of things security work.
