Metal Detector Circuit Diagram Using Ic 555

2 2µf capacitor 2 pieces speaker 8ω 170turns of 10cm diameter coil any gauge would work circuit diagram and working.
Metal detector circuit diagram using ic 555. The above circuit shows a schematic diagram of the metal detector. The operation of metal detectors is based upon the principles of electromagnetic induction. The proximity at which the detectors can detect metals depends on the detector s range it can cover. 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.
Dual flashing led circuit using 555 timer on breadboard basic electronics projects duration. Metal detectors contain one or more inductor coils that are used to interact with metallic elements on the ground. This metal detector circuit uses ic 555 chip along with an inductor was to build a cheap and simple metal detector at our home. 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.
Electronic circuits that use the ic 555 timer a simple metal detector electronic project can be designed using a simple 555 timer circuit. This circuit detects metal and magnets. 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. How these two concepts are used together for a metal detector circuit is explained in working section of this project.

Circuit components 9 supply voltage. Ic 555 timer here it acts as a generator and generates rectangular wave pulses with audible frequencies for humans.
Ic 555 has tons of applications in day to life and that s the reason it is still a significant ic chip. In this video working of a 555 timer ic in astable mode is explained working of the metal detector circuit is demonstrated. The figure shows the circuit diagram of. Metal detectors are gadgets that is capable of detecting metal elements on a surface.
