Simple Metal Detector Circuit Using BC548 Transistor

Simple Metal detector circuits are portable electronic devices for finding the presence of any metal within close range. These instruments function by sensing changes in magnetic waves caused by being in near proximity to a metallic object. In this project we are going to build a simple metal detector circuit using a BC548 transistor.

Metal Detector Circuit using Single Transistor Tutorial

The search coil for this one transistor metal detector circuit is created by winding 16 turns around a diameter of 12cm spherical subject. This is often a bottle of juice or perhaps a square object which the coil could be built rounded later on. Make use of 4 pieces of tape or tape round the winding turns to keep them in position and glue the

Build A Four Transistor Metal Detector Nuts and Volts Magazine

The circuit can sense a soda can at a depth of six inches and metal pipes at an even greater distance. The unit is powered by two 9V batteries in series. The detector has a current draw of approximately 9 mA at 18 VDC. As a result the batteries should last a long time. FIGURE 1. Four Transistor Metal Detector Schematic.
