About Metal Detector Project

They are used for the safety of people to detect anyone carrying a metal arms etc.

About metal detector project.

A simple metal detector uses a 555 timer ic. You can find a metal detector at airports theaters and various other public places. Many people get addicted to metal detecting. Assembling your own metal detector can be a great hobby or school project.

This could be a fun project for a young hacker to learn basic electronics. Building your own metal detector is fun and educational. Though very ancient it still has many uses. 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.

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. There are so many metal detector designs but most of them are complex in design so here we are going to. There is need for any microcontroller as the proximity sensor will be sufficient to implement the project.

The metal detector circuit is the mandatory part of the security. A metal detector is a circuit that senses any metallic object close by. 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. These metal objects are very useful to detect the presence of any hidden object.

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. And then hunt for buried treasure in their backyard. In this project we are going to design a simple metal detector circuit. They use it to prevent any unlawful entrance of guns and bombs in public places.
