Pi Metal Detector Schematic

The kkmoon metal detector check it here on amazon is one of the cheapest yet reliable pi detectors in the market.

Pi metal detector schematic. Pulse induction pi metal detectors are sending repeated pulses of electrical current to the search coil producing a magnetic field. Completed surf pi 1 2 pulse induction metal detector kit circuit board solder side click for full size image after you have finished soldering all the components onto the board its time to connect wires from the supplied plugs and terminals to the molex connectors. The coil transmits a pulse toward the ground generating an answering pulse from the target object. It does include most features that you will require for hunting.

There is need for any microcontroller as the proximity sensor will be sufficient to implement the project. Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced. Schematic diagram of white s surfmaster pi metal detector a good quality simple pi pulse induction design with an affordable price. Detects all metallic objects with unbelievable depth and sensitivity on the hardest to hunt black sand beaches and in wet salt.

A sampling circuit measures the pulse and sends it to an integrator which generates an audio tone.
