Pulse induction metal detector, built on the Arduino Nano.
Project showcase by Alexey
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.
Here we use PIR sensor and Arduino to detect the motion of a hand. This detection can be used to operate electronic equipment.
