Metal Detector Using 555 Timer with Proteus Simulation

・2 min read

Hello Fellows! During this project, we've got designed a straightforward DIY metal Detector Circuit victimization terribly simple parts that may be utilized in our homes and gardens. Let’s begin our tutorial.


The first industrial sensor was appear within the year 1960 and was utilized for mineral prospecting and other industrial applications. A sensor is Associate in nursing device that features Associate in nursing generator that produces AC that passes through a coil manufacturing Associate in nursing alternating magnetic flux. If a locality of the metal is on the subject of the coil, eddy current are going to be elicited within the metal and this produces a magnetic flux of its own. If another coil is employed to live the magnetic flux, the amendment within the magnetic flux, the amendment within the magnetic flux thanks to the metallic object are often detected. The metal observers are accustomed detect the weapons like guns, knives within the airports, and conjointly utilized in the development trade to observe steel reinforcing bars in wires, concrete, pipes buried in floors and walls.

Components Required:

555 Timers

Circuit connection in Proteus :

The 555 Timers has total 8 pins. Its 2 pin is attached with capacitor. Pin 1 is connect with GND. Pin 8 is connect with battery 12v. While Pin 6 is connect with capacitor, resistor and inductor. Pin 3 are connected with capacitor and also with speaker.

Working of circuit Simulation:

The sensor operating is, once the magnetism field is transmitted from the search coil into the world. Metals within the magnetism field can become strong & resend Associate in nursing magnetism of their own. The sensor includes of a probe coil that receives the retransmitted field & alarms the user by generating a response of the metal. Mine lab metal detectors are accomplished by discriminating between dissimilar sorts of targets and might be fastened to ignore unwanted metal objects. Applications:
• This straightforward sensor are often accustomed establish metals like iron, gold, silver etc.
• Since it's a straightforward project, we will use this in our home to scan for nails, metal scraps etc. that don't seem to be simply spot able by eye.
Hope this text provides you provided you with temporary data concerning the sensor circuits and its principle of operation.
