Pulse induction metal detector, built on the Arduino Nano.
It can detect metal coin at 15cm +, and bigger metal objects at 50cm and more. Also capable of discriminating between ferrous and nonferrous
Pulse induction Metal Detector. It can detect a metal coin at a distance of 15 cm and a larger metal object at a distance of 40 cm and more.
The construction is really simple thanks to the microcontroller, but also the module for weak signal amplification with LM358 IC.
The detector can detect a small metal coin at a distance of 15 centimeters.
Cool little Pocket Metal Locator sensitive enough to identify small nails and tacks in wood with four independent search coils and LEDs.
Despite its simplicity, it has a relatively good sensitivity and perfect stability during operation
Simple metal detector capable of detecting a small coin at a distance of 4-5 cm.
