When leaving the the capacitor, then you would be talking about a standard PI detector. As the standard PI-detectors do have the problem of the inverted pulse after switching off the FET, you are back to the standard design with a additional supply voltage (e.g. GoldPic), with a decoupling condenser (e. g. Pirat) or to the Flip-Coil design of my other instructable. As I said, I am working on a ...

A pulse induction (PI) metal detector can be very easily implemented with a single GreenPAK configurable mixed-signal IC . Pulse induction designs have the advantage of tolerance to ground effects, and work even when submerged in water. It also performs well on non-ferrous metals. This tutorial uses an analog comparator, digital timing vernier and digital averaging to provide an LED bar ...

PI Technology - PI Metal Detectors | …

PI-based detectors are not very good at discrimination because the reflected pulse length of various metals are not easily separated. However, they are useful in many situations in which VLF-based metal detectors would have difficulty, such as in areas that have highly conductive material in the soil or general environment. A good example of such a situation is salt-water exploration. Also, PI ...

Metal Detectors - Theory and Practice - VLF, PI …

Pulse Induction (PI) metal detectors are sending repeated pulses of electrical current to the search coil, producing a magnetic field. The coil transmits a pulse toward the ground, generating an answering pulse from the target object. A sampling circuit measures the pulse and sends it to an integrator, which generates an audio tone.

Metal Detector using Arduino - Engineers Garage

The Arduino based metal detector explained in this project is basically a frequency meter which measures the resonating frequency or time period of a tank circuit. The resonating frequency of a tank circuit is fixed however the presence of metals can vary it slightly. The tank circuit is a general term representing an inductor and a capacitor connected in parallel. This circuit is also called ...

Traditional BFO (beat-frequency oscillator) metal detectors overcome this problem by incorporating another tank circuit with a fixed frequency equal to the frequency of the detector tank circuit without the influence of any metals. Then, taking the difference between the two frequencies will isolate the fluctuating frequencies of the detector circuit and bring it down to an audible range.
