About Metal Detector Project

This is a simple metal detector circuit can find various metal and adjustable sensitivity easy to use to place near metal.

About metal detector project.

In this project we are going to design a simple metal detector circuit. Metal detectors are useful for finding metal inclusions hidden within objects or metal objects buried underground. A metal detector is a circuit that senses any metallic object close by. They often consist of a handheld unit with a sensor probe which can be swept over the ground or other objects.

For this metal detector project we will be using an arduino to process the oscillation signal instead of offsetting the oscillation with a second tank circuit. They use it to prevent any unlawful entrance of guns and bombs in public places. You can find a metal detector at airports theaters and various other public places. This could be a fun project for a young hacker to learn basic electronics.

Many people get addicted to metal detecting. They are used for the safety of people to detect anyone carrying a metal arms etc. A simple metal detector uses a 555 timer ic. Though very ancient it still has many uses.

The arduino will store the fixed frequency and continuously compare the incoming frequency of the detector circuit with the stored frequency more on the arduino program below. The proximity detector ic tda0161 based metal detector circuit is a very simple and easy to construct metal detector that can be used to detect small metals in our homes offices and gardens. Assembling your own metal detector can be a great hobby or school project. Building your own metal detector is fun and educational.

There is need for any microcontroller as the proximity sensor will be sufficient to implement the project. These metal objects are very useful to detect the presence of any hidden object. There are so many metal detector designs but most of them are complex in design so here we are going to. The circuit inside includes a few components has ic ne556 is at the heart of the circuit with a principle of monostable multivibrator then show on moving coil type meter.
