06/01/2020· A metal detector is a circuit that senses any metallic object close by. These metal objects are very useful to detect the presence of any hidden object. A simple metal detector uses a 555 Timer IC. The Metal detector circuit is the mandatory part of the security. They use it to prevent any unlawful entrance of guns and bombs in public places. This is specially designed
DIY Metal detector project with PIC12F1572 microcontroller. This is open hardware DIY project. It is possible to make either pinpointer or a full size metal detector based on this circuit. Ported to the PIC12F1572 at 6.08.2107. PIC12F1840 still usable also. Figure 1. This is the circuit: Features: Very easy to build.
03/10/2014· The metal detector circuit is basically two oscillators designed using two transistors T 1 and T 2. One oscillator is working at 455 KHz and other at a slighter lower frequency of 452 KHz. IF transformer IFT 1 utilize an oscillator and coil L 1
05/04/2020· Description. This is the circuit diagram of a low cost metal detector using a single transistor circuit and an old pocket radio. This is nothing but a Colpitts oscillator working in the medium band frequency and a radio tuned to the same frequency. First, the radio and the circuit are placed close.

Below is the complete electronic circuit for the metal detector that we are building: Inductor L1 The inductor L1 forms a parallel circuit with the capacitor C1 to form an LC parallel circuit. When a signal that oscillates at several KHz passes through this circuit, the signal creates an electric field around the coil.
28/01/2021· This circuit really is the simplest inducer balancing metal detector that can be built. The LB metal detection method has a satisfactory depth of penetration and good distinction between. iron based and noble metallic objects. Several metal detectors are available in the market, but their price.

Metal Detector Circuit
metal detector circuitComponent DescriptionMetal Detector Circuit ExplanationWorkingAdvantagesDisadvantagesApplicationsThe major metal detector element of the circuit is the LC Circuit, which consists of L1 and C1. The TDA0161 IC functions as an oscillator with the help of this LC Circuit, also known as a Tank Circuit or Tuned Circuit, and oscillates at a specific frequency. When the LC circuit detects a resonating frequency from a metal that is close by, an electric field is formed, causing current t
