How does metal detector works? fully explained

metal detector circuit

Introduction: A metal detector is a device that can detect metal which may not be seen directly. The simplest kind of metal detector can be made using an oscillator, two inductor coils, and a detector or indicator. Here we will talk about how does metal detector works it’s construction applications and the importance of metal detectors in our normal life. For better understanding, you can watch this video? Components required: 1- Transistor BC 547 2- Transistor S9012 × 2 3- Electrolytic capacitor100uf 4- Resistor200k 5- Resistor 2k 6- Resistor 470…

Bc547 transistor project

Bc547 Transistor pinout

here are the Top 5 DIY bc547 transistor project for you. Bc-547 is an NPN bipolar junction transistor(BJT). It is widely used for power amplification and switching. The word transistor means of two words, transfer and resistor. The use of a transistor is to transfer the resistance. In transistors, a small amount of current at the base terminal controls a larger amount of current at the emitter and collector. BC547 has three terminals as in other transistors. 1. collector terminal 2. base terminal and 3. emitter terminal respectively.   The…
