Electronic circuits that use the ic 555 timer a simple metal detector electronic project can be designed using a simple 555 timer circuit.
Metal detector circuit diagram using ic 555.
The single coil detector illustrated below is a simplified version of one used in a real metal detector.
Metal detectors are gadgets that is capable of detecting metal elements on a surface.
Ic 555 has tons of applications in day to life and that s the reason it is still a significant ic chip.
Dual flashing led circuit using 555 timer on breadboard basic electronics projects duration.
The circuits explained here are 10 best small timer circuits using the versatile chip ic 555 which generates predetermined time intervals in response to momentary input triggers.
Here in this metal detector circuit we are using a timer ic 555 and inductor to detect metals and alert the user by means of an alarm from simple buzzer.
The figure shows the circuit diagram of.
Ic 555 timer here it acts as a generator and generates rectangular wave pulses with audible frequencies for humans.
How these two concepts are used together for a metal detector circuit is explained in working section of this project.
The above circuit shows a schematic diagram of the metal detector.
The time intervals can be used for keeping a relay controlled load on or activated for the desired amount of time and an automatic switch off once the delay period.
Metal detectors contain one or more inductor coils that are used to interact with metallic elements on the ground.
Circuit components 9 supply voltage.

This metal detector circuit uses ic 555 chip along with an inductor was to build a cheap and simple metal detector at our home.
The proximity at which the detectors can detect metals depends on the detector s range it can cover.
There are so many metal detector designs but most of them are complex in design so here we are going to design a simple metal detector circuit using 555 timer ic.
As you can see in the schematic circuit this project requires some external electronic electronic parts.
